Yes this is normal. Many women complain of very erect and sensitive nipples after breast implant surgery. You can protect your nipples by using a Band-Aid (especially the large round ones), large corn pads, or nursing pads. These pads will protect your overly sensitive nipples from the abrasiveness of your clothing and shield your erect nipples. In addition, you may lose some sensitivity in the nipple or the surrounding skin after breast augmentation surgery. This usually subsides within a few weeks. In rare cases, however, loss of sensation can be permanent. As sensation returns to your nipples and breasts, you may experience sharp pains, itching, heat, tingling and prickling. These temporary sensations occur because nerve function is returning.
