I have a very tiny hole on my skin, the size of ant. its slightly under my right breast. There is a hard bump near the hole deep under the skin. The bump is slightly hard and the size of a thumbnail. Nothing has ever leaked out the hole, but the bump underneath was a little bit painful when it first showed up. Now I don t feel it anymore. I ve had an ovarian cyst before and ones under my arm a few times but they went away on their own. And the ones under my arm have never had a hole before. i went to the doctor to have a biopsy on it but they have yet to contact me about it. Do you have any idea what it could be?
