Thank you for your question. Nipple sensitivity usually resolves at 12-18 months. Nipples can either be more or less sensitive, but usually resolve. Avoid excessive irritation as the nerves heal. Unfortunately, nerves heal slowly. I hope this helps.
Hypersensitive Nipples are common after breast augmentation. The nerves that provide nipple sensation are stretched and "irritated" by breast augmentation surgery. As they recover they are often hypersenstiive. This almost always recovers. What generally works for my patients (and applies to senstiive scars as well as hypersensitive nipples) is a program of active desensitization, by consciously touching and massaging the area with mosturizing cream and or body oil. Our natural reaction to supersensitive areas is to avoid touching them, which is the opposite of what we need to do. Check with your plastic surgeon first, but simple desensitization may well do the trick for you. Good luck.
