Hello,

Welcome to icliniq.com.

I understand your concern.

I would like to know a few details, like

  • Since when has he noticed this swelling?
  • Is there swelling anywhere else, like in the neck or armpits?
  • Any fever, cough, throat pain, or weight loss?
  • Any history of TB (tuberculosis), smoking, or tobacco?
  • Any ulcer in the mouth?

There can be a few reasons for this swelling like:

  • Reactive due to the swollen tooth.
  • Viral infection of the throat.
  • Scalp infection.
  • Cancer of the oral cavity or lymph nodes.

What I will advise you is to complete the treatment for the swollen tooth and also take a course of antibiotics for the same. If the swelling is still persistent, then you need to get it checked. The best thing is to see a physician who will examine you in detail and also to get basic blood tests like CBC (complete blood count), ESR (erythrocyte sedimentation rate), LFT (liver function test), and a chest X-ray. He might also need an FNAC (fine needle aspiration cytology), depending on what his symptoms and reports are.

For more information, consult an internal medicine physician online.

Thank you.
