Hi,
Lump under the nipple appearing after nipple piercing should be related to it. It could be haematoma. Since it is present for a longer duration , organized haematoma could be considered.
Other possibility could be an allergic reaction to the ring leading to granuloma formation.(Foreign body reaction)
Next possibility could be a fibroadenoma.
Hence have an clinical examination done by a surgeon at the earliest.
Hi,
It could be that the nipple ring is responsible for the lump. It could be allergic reaction to the ring itself, or it could be a superadded infection - bacterial mostly due to the piercing process that has manifested late, or it could be an inflammatory lesion due to the ring. A nipple ring after piercing causes a lesion that takes several months to heal and there is always the chance of a superadded secondary infection. As a first measure you could do away with the nipple ring and see if the lesion heals. Also try some local soothing oitntments too. Have you noticed the knot increasing in relation to your menstrual cycle? Anyways if the nipple ring is not the cause, the lump needs to be investigated further to rule out a malignant lesion and then further management planned accordingly. If the knot still persists, then you would have to go for a clinical evaluation and further investigations and see what your physician has to say. Goodluck.
