Hi, Welcome to Health care magic forum.
As you describe, it appears that you have some allergy
, in the head area. Or may be secondary to some infection on the scalp
may not have any relation.
I advise you to consult a physician for diagnosis and treatment.
Take more of green leafy vegetables,pulses,sprouts, and protein rich foods to have good health and resistance.
Wishing for a quick and complete recovery. Thank you.
