I had some cosmetic surgery 9 months ago, & a tiny piece of string festered and came out of my neck. now i have what appears to be a large pimple on my neck in another spot, that has a very hard bump under it that festers daily and white puss comes out after squeezing it. could this be a staff infection or maybe another piece of string trying to come out? it has been there for over a month. it is embarrassing. it does not itch nor spread, but doesnt go away. the hard bump was there first, and originally i was told it was probably just fluid that had dried, and to massage it. that has not worked. i will not go back to the doctors that did it due to legal issues.
