UKcyclinggirl - I'm having problems with this also. I have two areas under the skin that rub when I ride. I sure wish they would come to the surface and erupt so that the healing process would begin. I had a sebaceous cyst several years ago that took forever to open up to the skin surface. Once it drained, it sealed itself off and was almost instantly healed.
I saw my doctor about a month ago and she showed no interest in doing anything about it. If the bumps are still there in the spring, I may have to clearly ask her to lance and drain them. Riding is uncomfortable because of the tenderness, but I'm not going to stop cycling.
My bumps are in such a hard place to see that I can't imagine draining them myself. I'd end up standing on my head!
The joys of riding.
