Sorry to hear about your problem. Your symptoms are suggestive of eczema
of the nipple, which is a common problem in women your age. It manifests as severe itching
and scaling of the nipple and areola
. PCOS has no correlation with this condition and management for PCOS will not affect this condition. You need to consult a breast surgeon for this problem, as he/she would rule out a lump in the breast and then start you on local steroid
cream, which is the treatment for this problem.
Hope you get well soon.
