Hi,

Thanks for the query.

Your lump in neck and below the jaw could be lymph node secondary to infection in throat.
Commonly acute throat infection is due to viral but may get secondary bacterial infection.
You need to visit Physician and after examination, prescription of antibiotic, decongestants, and anti inflammatory drugs for the same.

In the meantime you can take paracetamol for pain and fever. Do warm saline gargles three time a day, which will help to reduce congestion in throat.

This may take few days to resolve and hope you recover soon.

Hope this information helps you. If there is any further query, I will be available for clarification.

Regards.
Dr.Akhilesh Dubey M.D.
