Hi, Welcome to Health care magic forum.
As you describe it appears to be negative for
tuberculosis, and had treatment for that. The causes for the
lymph gland in the neck may be
head lice, or any infection near to that gland, either dental,mouth, nose, or ear.
Or there may be the
fibrosis of the lymph gland, and contracture of the tissues.
I advise you to consult an E.N.T. surgeon for diagnosis and treatment.
I usually prescribe to my patient with such symptoms
ascorbic acid 500mg once daily for 10 days to relieve the
contractures.
Take more of green leafy vegetables, pulses, sprouts,and
protein rich foods to hasten the recovery.
Wishing for a quick and complete recovery. Thank you.
