I have a swollen lymph node in left jaw since 3 weeks with no other symptoms but headache. I took antibiotics and was on trypsin for swelling after completing the antibiotics course. I also got blood test and ultrasound done which shows cervical lymphadenopathy ( B/L parotid and submandibular glands show normal homogenous echo-pattern. No focal lesion is seen. Multiple subcentimetric bilateral cervical level 1A,IB ,IIA lymph nodes are seen with some of them showing loss of fatty hilum largest measuring 7mm in SAD . Few subcentimetric lymph nodes are seen at the site of palpable swelling largest measuring 6.4x4.2). Blood tests came normal with MPV (14.8) and platelets (33000) . Am worried why the swelling is not going.
