Hello,
Chicken pox scars are very tough to treat. Apply hydroquinone cream or creams containing vitamin E on the scars. If it still persists then you can go in for laser treatment, photodermabrasion or microdermabrasion. Avoid picking, harsh scrubbing, and abrasive treatments unless prescribed by a dermatologist during this period.
It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your dermatologist. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.
None that I know of. But the scar will fade with time.
