Since last 3-4 months I am having severe acne issues before my period due dates. It usually at two places all the time. One around my red cheeks and on the chin. It's unusual. 3-4 months back my period cycle change unexpectedly and my periods use to come twice a month. Had this problem for 2 months. And now my period cycle is fine but my acne issue has not stopped. I need a good dermatologist with a good experience who can suggest me how to avoid period acnes

Hello Doctor, We got to know that my mom has got herpes. Outbreak is almost over now, swelling and blisters are all reduced but she is still getting severe headaches. Also she is now getting crawling and itching sensation on all the infected areas. She is on acyclovir medicine for almost 20days now, headaches are back if she stops taking the pill. Please suggest on the pill usage and about these sensations. Anything can be done to relieve this pain? We have visited multiple hospitals and everywhere it's same medication. Any suggestions would be appreciated. Thank you.
