Recently, I had a small cyst near my rectum. About 3-4 days ago, I was cleaning it and it unexpectedly popped. I quickly grabbed tissue to clean it, but nothing came out. It apparently popped under the skin. Since that happened, the cyst is gone, but now I seem to have a hard, swollen vein in my taint area. Is this common or something I need to see a doctor about? I m almost 40, so the thought of my prostate came to mind as well. Thanks for any help on this!
