Thanks for posting question on HCM,
You are probably suffering from acne
of comedonal type (mostly black heads) start applying retin A
cream at night daily,clindamycin
gel in day and oral doxycycline 100 mg daily for 1month then let me know.
Acne usually develops at puberty
but some times late,it may run from 25-30 years and present as blackheads ,whiteheads,pustules and sometimes cysts on face and shoulders.There is no need to avoid any particular food.
Hope this will alleviate your anxiety
