Dear Madam You seem to have a condition in which irregulary sized patches of baldness occur in the hairy areas that are usually without pain itching or flakiness but sometimes new lesions may have itchiness.This is called Alopecia Areata and it responds very well to topically applied irritants like Tincture or injections of steroids directly into the spots. It is a procedure that is comfortable tolerated. no worries on that account.Results are highly encouraging. you please consult your dermatologist and first get yourself diagnosed definitively and then seek treatment as per your requirements. you stand a good chance of being alright again. Have a great time.
