Some patients albeit pretty rare get hypersensitivity in the nipples after breast surgery. Some can be recalcitrant to therapy. Probably the best person to see is a pain specialist.

Pain in the Nipples Never Ended
If you have exhausted all the remedies from your plastic surgeon, seeing a pain specialist might offer useful help. Occasional one or a few nerve blocks with local anesthetic can break the cycle. There are some medicines, such as neurontin that can be tried.
See a doctor who regularly takes care of pain patients in his/her practice makes most sense to me.
Thanks and best wishes.
