Can Allergies Cause Swollen Lymph Nodes
Swollen lymph nodes are a sign that your body is fighting off an infection. Can allergies cause swollen lymph nodes too? Some people might experience this, but its not common. Instead, you are more likely to experience the symptoms listed above. If your allergies are causing swollen glands, then you may also have an infection, such as a sinus infection. These can happen while you are dealing with allergy symptoms.
An Autoimmune Disorder Could Be The Culprit
An autoimmune disease is a misfiring of the immune system, causing it to attack healthy organs, tissues, or cells. According to the National Institutes of Health, there are more than 80 known autoimmune diseases, including psoriasis, celiac disease, type 1 diabetes, lupus, and rheumatoid arthritis .
That overactive immune system can cause lymph nodes to swellfor instance, in cases of lupus and RAbut not all of these diseases have enlarged lymph nodes as a symptom. Autoimmune disorders can be tricky and frustrating to diagnose if youre concerned, talk to your doctor, who will typically look at your constellation of symptoms, which can range from joint pain and swelling to constant fatigue, depending on the specific disease.
What Else Can Cause Swollen Lymph Nodes
There are many other possible causes of swollen lymph nodes, including:
- infections, such as coughs, tonsillitis, colds, ear and throat infections
- illness that affect the immune system, such as rheumatoid arthritis
- skin conditions, such as eczema or psoriasis
- some medicines, including penicillin, drugs used to treat epilepsy , cephalosporins and the covid-19 vaccination.

What Is The Lymphatic System
The lymphatic system is a network of tissues and organs. They rid the body of waste, toxins, and disease-causing bacteria. The main function of the lymphatic system is to carry lymph through the body. These white blood cells help fight infection. Therefore, the lymphatic system functions as a military transport. The lymph nodes act like military checkpoints. The nodes stop bacteria and abnormal or diseased cells as they pass through it.
The lymphatic system has lymphatic vessels, which are similar to the blood vessels like veins and arteries. The vessels lead to nodes which filter the lymph. This means that whenever there is an infection or a tumor, the lymph nodes will swell. This happens because of accumulated debris, such as bacteria and dead or diseased cells. The swelling of lymph nodes is called lymphadenopathy. It can be localized or generalized .
Tonsils, adenoids, spleen, and thymus are all part of the lymphatic system.
Diagnosing Swollen Lymph Nodes
If you experience the symptoms described above, then you can visit a physician for a preliminary exam. Besides conducting a physical examination, they will ask you about your symptoms and your medical history to diagnose the cause of the swelling. They can also order a routine blood test or an imaging test as part of the diagnosis.

Why Does Lymphoma Cause Swollen Lymph Nodes
Swollen lymph nodes in lymphoma are caused by a build-up of cancerous cells in the lymph nodes.
Sometimes the lymphoma is active, which means that its making lots of cancerous cells. At other times, its less active, and some of the lymphoma cells die. Lymph nodes sometimes grow and shrink , especially in people with low-grade non-Hodgkin lymphoma.

Preventing Infection And Injury
Protecting the arm on the side of the surgery is very important after breast surgery. Poor drainage of the lymphatic system can cause that arm to be more at risk of infection and less sensitive to extreme temperature. Be aware of activities that put too much pressure on the affected arm. To protect your arm from injury and infection, make sure to do the following:

Dysfunctional Breathing Or Hyperventilation Syndrome
This condition may affect up to 10% of the population and is more prevalent in women and asthma patients . Attacks of hyperventilation can be confused with asthma, both in patients with and without an actual asthma diagnosis. Patients frequently over-breathe or have an increased respiratory rate. Hyperventilation syndrome occurs when minute ventilation exceeds metabolic demands, resulting in respiratory alkalosis leading to dyspnea and chest tightness. It may often occur during acute anxiety, mimicking asthma . Spirometry at the time the patient is symptomatic can help distinguish the perception of dyspnea associated with a hyperventilation attack from asthma. There is no criterion standard to establish the diagnosis, however, in the presence of normal pulse oximetry during ambient air respiration a blood-gas measurement that demonstrates a low PCO2 and high pH at the time of symptoms provides more supportive evidence for hyperventilation. Breathing retraining by a physiotherapy intervention and anxiolytic therapy can significantly improve health-related quality of life scores .
Symptoms Of Swollen Lymph Nodes
The most common signs are:
Tenderness or pain in your lymph nodes
Swelling that makes your lymph nodes the size of a kidney bean or possibly larger
Because swollen lymph nodes are usually linked to some type of illness, you might also have other symptoms, depending on what that illness is:
Runny nose, sore throat, or fever
Swelling of clusters of lymph nodes in different places in your body
Hard lymph nodes that wonât move or get bigger quickly

Cancers Lymphomas And Leukaemias
Some cells from a cancer can break off and spread to nearby lymph glands via the lymph channels. These cancer cells then grow and multiply in the lymph glands and cause the glands to swell. For example:
- Breast cancer may spread to the lymph glands in the armpit.
- Throat cancer may spread to lymph glands in the neck.
- Lung and stomach cancers may spread to lymph glands that you usually cannot see or feel in the chest and abdomen.
- Skin cancers may spread first to the closest lymph glands to the area of skin involved.
- Cancer of the lymphatic and blood systems can cause many lymph glands to swell.
As a rule, swollen lymph glands due to cancers, lymphomas and leukaemias develop more slowly than those due to infections. They also tend to be painless at first.
Causes Of Swollen Lymph Nodes
Many different conditions cause the lymph nodes to swell, particularly the nodes in the head and neck. These conditions include autoimmune disorders, specific types of cancer, and common infections, such as the flu. Certain medications, such as antimalarials and antiseizure drugs, can also cause swelling.
Most people have localized lymphadenopathy, in which only the lymph nodes in one particular area of the body swell up. When more than one region swells, this is called generalized lymphadenopathy, and it usually signifies a systemic, or body-wide, disease that may require medical attention.
In the following sections, we discuss the possible causes of swollen lymph nodes in more detail.

The Symptoms Of Swollen Lymph Nodes
Swollen lymph nodes are usually detected through physical examination. They feel like soft, circular bumps. You can gently press areas like the side of your neck to see if there is swelling. Some people experience tenderness in their lymph nodes and may experience pain when they are chewing food or when they turn their neck in a certain direction. Swollen lymph nodes in the groin area may cause pain when you walk or bend.
You should consider visiting a physician if the swelling has not reduced after a few weeks or has increased, if the lymph nodes feel hard when you press them, if you have difficulty swallowing or breathing, and if you have a sore throat. Swollen lymph nodes accompanied by weight loss , and a persistent fever is also a source of concern.
What Causes Swollen Lymph Glands
Lymph glands are normally pea-sized. You can sometimes feel them as lumps under the skin. People often feel their lymph glands in the neck. Lymph glands under the skin become more noticeable and easier to feel if they swell. They can swell to the size of marbles or even bigger.
You cannot see or feel lymph glands that are deeper in the chest or tummy but they may be uncomfortable or tender.
Causes of swollen lymph glands include the following:

How Are Swollen Lymph Nodes Treated
Treatment for swollen glands focuses on treating the cause. For example, a bacterial infection may be treated with antibiotics, while a viral infection often goes away on its own. If cancer is suspected, a biopsy may be done to confirm the diagnosis.
Any swollen lymph nodes that don’t go away or return to normal size within about a month should be checked by your doctor.
Eosinophilia: 9 Causes Symptoms Diagnosis And Treatment
Eosinophilia is the term used to denote increased eosinophil count or increased eosinophils in the blood. But, do you know what are eosinophils? Let us see below.
What are Eosinophils?
Our blood has three types of cells, white blood cells, red blood cells and platelets. The white blood cells are part of our immune system, which protects us from various diseases. White blood cells further include various types of cells like Eosinophils, Basophils, Neutrophils, Lymphocytes and Monocytes.
So, Eosinophils are a type of white blood cell and part of our immune system. They help in protecting us against various parasitic infections and they also take part in various allergic reactions that occur in the body.
What are Symptoms or Eosinophilia or elevated Eosinophil count?
The most common symptoms of Eosinophilia are:
- Itching throughout the body

When To See A Doctor For Swollen Lymph Nodes
In most cases, swollen glands return to normal size after the illness or infection has passed. But here are some things to watch for:
Glands that swelled up very suddenly
Glands that are much larger than they should be, not just mildly swollen
Glands that feel hard or don’t move when you push on them
Glands that stay swollen for more than 5 days in children or 2 to 4 weeks in adults
The area around the glands turns red or purple, it feels warm or you see pus
Swelling in your arm or groin
Sudden weight loss
If you notice any of these, see your doctor.
How To Check Your Lymph Nodes
You have been diagnosed with a skin cancer that on occasions can spread into the lymphatic system. That is why as part of your examination your lymph nodes are examined by your doctor or Skin Cancer Clinical Nurse Specialist at follow-up appointments. The lymph nodes examined depend on the location of your skin cancer e.g. if your skin cancer was on your leg then the lymph nodes in your inguinal area will be felt or if on your face then the nodes in the head and neck would be examined. The aim is to detect any enlargement of the lymph nodes and undertake investigation at an early stage. Some people express a interest in knowing which lymph nodes to examine and how to undertake this procedure between clinic appointments.
The Lymphatic System
This system consists of lymphatic vessels and tissue which drains lymph fluid from the tissues of the body, helping to protect you from infection and disease. Lymph nodes are small oval lumps of lymphatic tissue found at certain parts of the body.
These lymph nodes filter out bacteria and disease cells from the lymphatic fluid before it is returned to the blood stream. Lymph nodes can only be felt in the areas shown in the diagram.
Usually lymph nodes are not enlarged and thus not able to be felt, but if you have previously had an infection you may have noticed and felt lymph node becoming enlarged, painful and tender. Lymph nodes can also become enlarged due to cancer cells lodging in them.

How To Prevent Enlarged Lymph Nodes In Dogs
Some dog breeds appear to have a genetic predisposition for developing lymphoma, but no one knows for sure. These breeds may include Golden Retrievers, Boxers, Bullmastiffs, Basset Hounds, Cocker Spaniels, Irish Wolfhounds, Saint Bernards, Scottish Terriers, Airedale Terriers, and Bulldogs. If a dog has a history of lymphoma they should not be bred.
Other reasons for lymph node enlargement are difficult to prevent. Overall, doing what you can to help keep your dog healthy can help decrease the likelihood of infections that may result in lymph node enlargement. Immune supplements, proper nutrition, regular veterinary attention, and practicing good hygiene are all things that may aid in your efforts.

When To See A Doctor
People should see a doctor if they have persistently swollen lymph nodes that do not lessen over the course of a few days, or if the lymph nodes are painful or causing discomfort.
Treatment for swollen lymph nodes depends on the cause. For instance, cellulitis or skin infections usually require antibiotics.
Jock itch or athletes foot may clear up with antifungal medicines. If there is no clear cause of an infection, a doctor may run tests for other conditions.
After treating the underlying cause, the swollen lymph nodes will go back to their normal size.

Swelling In The Arms Or Legs
Swollen lymph nodes can sometimes block the lymphatic vessels . This stops the lymph fluid draining properly from the tissues in your body.
The lymph fluid can then build up, causing lymphoedema . Possible symptoms include swelling, feelings of tightness, heaviness, aching or soreness. It usually affects an arm or a leg, although it can affect other areas of your body, depending on where the lymphoma is.
Other conditions can also cause lymphoedema. For example, infection, injury, genetic conditions and surgery.
If you have any symptoms of lymphoedema, speak to your GP.
Diagnosing The Cause Of Enlarged Lymph Nodes In Dogs
If your dog has enlarged lymph nodes your vet will first perform a physical examination. This will help determine how many lymph nodes may be affected and what the reason for the enlargement may be.
Blood tests to check organ function and white blood cell numbers are typically run but a fine needle aspirate will also be recommended. This involves inserting a needle into the lymph node in order to collect cells that may indicate the reason for the enlargement. If the FNA is inconclusive, a lymph node biopsy may be performed under anesthesia. This will allow a better look at the lymph node tissue.
Further tests may be needed for various infections depending on what your veterinarian suspects based on symptoms and test results. These may include a urinalysis, fecal test, X-rays, and ultrasounds.

Chemotherapy With Or Without Radiation Therapy
Chemotherapy is used for all stages of disease. Doctors usually use more than one chemotherapy drug. Several combinations may be used and may include immunotherapy drugs as well. Immunotherapy drugs are made up of antibodies that attack cancer cells. Involved field radiation therapy may be added after chemotherapy. Radiation therapy is usually given on an outpatient basis over about 3 to 4 weeks.
About 85% of people with stage I or stage II disease are cured with chemotherapy alone or with chemotherapy plus involved field radiation therapy. The cure rate of people with stage III disease ranges from 70 to 80%. Cure rates for people with stage IV disease, while not as high, are above 60%.
Although chemotherapy greatly improves the chances for a cure, side effects can be serious. The drugs may cause
