Swelling near nipple
From recent couple of days i am having a feeling that there is a mild swelling under the skin just above my areola.. it hurts when pressed and the swelling cant be felt frpm merely looking at it if touched then one can say the area is raised a bit.. There is no other change.. Nothing.. Rest is absolutely fine.. it is unlikely to be a lump the area is soft and hurts when pressed hard.. There is no other visual change and it is on the right side only.. What is this???
