Hello. : Hello. First off, i want to let you know that i cannot tell you the reason for your nipple soreness. A common reason for nipple pain is skin abrasion from friction. This can be due to a bra that doesn’t fit well or physical activity with a bra that is not adequately supportive or physical activity (like bouncing) without a bra. It doesn't really sound like this, since you were specific that the pain is deep to the nipple if this were the cause it should clear up within a couple of days. Other causes can be an abscess, infection of the duct, inflammation of the duct or possibly cancer. If you have redness, heat, swelling, a lump, bloody nipple discharge, fever or chills or the skin is cracking, then you should contact your doctor now. Take care.
