Explanation

Unilateral tonsil swelling means that one tonsil is bigger than the other. This can happen for a few reasons.

Possible Causes:

  1. Infections: Sometimes, infections like a sore throat or an abscess can make one tonsil swell.
  2. Tumors: In some cases, a growth or tumor could be the reason. This includes both non-cancerous and cancerous types, like lymphoma.
  3. Other Conditions: Other medical issues might also cause one tonsil to enlarge, such as certain immune system problems.

Importance of Medical Evaluation:

It's important to visit a doctor if one tonsil is swollen. They can help figure out why it is happening and what treatment might be needed. Remember, only a healthcare professional can provide a proper diagnosis and treatment plan.
