Signs of swollen lymph nodes in groin

Swollen glands are a sign the body is fighting an infection. They usually get better by themselves within 2 weeks.

Check if your glands are swollen

Swollen glands feel like tender, painful lumps:

  • on each side of the neck
  • under the chin
  • in the armpits
  • around the groin

Glands (known as lymph glands or lymph nodes) swell near an infection to help your body fight it.

Sometimes a gland on just one side of the body swells.

You might also have other symptoms, such as a sore throat, cough or high temperature.

Things you can do yourself

Swollen glands should go down within 2 weeks.

You can help to ease the symptoms by:

  • resting
  • drinking plenty of fluids (to avoid dehydration)
  • taking painkillers like paracetamol or ibuprofen (do not give aspirin to children under 16)

Non-urgent advice: See a GP if:

  • your swollen glands are getting bigger or they have not gone down within 2 weeks
  • they feel hard or do not move when you press them
  • you're having night sweats or have a very high temperature (you feel hot and shivery) for more than 3 or 4 days
  • you have swollen glands and no other signs of illness or infection
  • you have swollen lymph glands just above or below your collar bone (the bone that runs from your breastbone to each of your shoulders)

Causes of swollen glands

Do not self-diagnose – see a GP if you're worried.

Swollen glands are:

  • often caused by common illnesses like colds, tonsillitis and ear or throat infections
  • sometimes caused by viral infections such as glandular fever
  • rarely caused by anything more serious, like cancer of the blood system (leukaemia) or lymph system (lymphoma)

A GP will be able to recommend treatment depending on the cause, which might include antibiotics (antibiotics do not work on viral infections).

Before we get into why lymph nodes swell, what it indicates and how to treat the condition, let’s quickly understand a little about lymph nodes in the human body. 

  1. Lymph nodes are small, peanut-sized (usually around 0.5cm) glands that play an important role in defending our body from bacteria, viruses, fungi, and other pathogens.
  2. The cells in our body dump waste (containing microbes and foreign substances) in the lymphatic fluid. 
  3. The fluid travels to the lymph nodes to undergo a filtration process.
  4. Lymph nodes filter out the waste stuff in the lymphatic fluid. Lymph nodes contain lymphocytes, a type of white blood cell that kills pathogens.
  5. When there is a lot of waste to be filtered, more lymphocytes are produced and this results in the swelling of lymph nodes.

Lymph nodes are present in the neck, armpits, groin, stomach, and between the lungs. Lymph nodes are categorised as cervical, axillary, and inguinal lymph nodes depending on their location. 

Signs of swollen lymph nodes in groin

What causes the lymph nodes in the groin to swell?

In short, if the lymph nodes are swollen, understand that your body is fighting an infection but may not be with much success. The infection could be due to an injury, STI, UTI or airborne like Corona. In some cases, even a simple fungal infection like jock itch can cause lymph nodes in the groin to swell. 

Common infections such as strep throat, measles, ear infections, infected tooth, viral infections (such as Herpes, HIV, Corona), skin infections can cause swelling of lymph nodes. Immune system disorders such as lupus and rheumatoid arthritis can also cause the swelling. Cancers that originate or spread to the lymph system cause the lymph nodes to swell.

Detecting lymph node swelling by yourself

Know that, in normal circumstances, lymph nodes are very small and movable. Most often, they are not larger than the nail of your little finger. Keeping that in mind, you can look for:

  1. Pain in your groin, under arms, near neck
  2. Since they lie just under the skin, you may be able to just see the swelling
  3. The area may be tender to touch and most often painful
  4. Moving a swollen lymph node is not as easy and you will find them hard on touching.

Diagnosis

Your doctor will start with a few questions about your current health, medications that you are taking, any recent encounters of unprotected sex or any injury or trauma that you may have met with.

Past that, a complete blood report / picture will be needed to see the levels of various cells in the blood. Increase in white blood cell count, decrease in lymphocytes etc kind of imbalances may signal at a possibly severe infection that your body is trying to fight off. Urine analysis may be required to check for Urinary Tract Infections. A pap test of the cervix, vagina, debris under the foreskin etc if your doctor suspects cancer.

Imaging tests such as CT or MRI may be requested to see the extent of swelling and also to look for the presence of malignant tumours in the body.

Treatment for swollen lymph nodes

The underlying cause is treated because swelling of the lymph nodes is most often caused by the invading pathogens. 

  1. If the infection is bacterial, antibiotics will be given depending on the type of bacteria. In some urgent cases, IV administration of antibiotics may be required.
  2. For fungal skin infections, antifungal cream or powder may be prescribed.
  3. For sexually transmitted bacterial infections, appropriate antibiotics (oral medicines) will be given.
  4. If the infection is caused by virus, antiviral medicines and for HIV, antiretroviral therapy will be the treatment path followed.
  5. If cancer is detected, treatment can involve chemotherapy, radiation therapy, surgery to remove the tumour(s), immunotherapy etc will be done.
