Ok so here is a question for all of you intelligent people. Not too long ago, I noticed a bump on my anus. It was a rather large bump, and it was not inside my rectum, but near the anus, in the buttcrack if you will. At first I thought the bump, which was somewhat large and slightly sensitive to pressure, could be a hemmhoroid. Following online guidelines, I rested in warm water and in time the bump went away. Occasionally, I get a bump again. These bumps do not seem to be a sort of std, such as anal warts, and I don't think that they are. They aren't, however, red and veiney like hemmhoroids have been described ass. The bumps are rather sturdy, as if they are somewhat calcified. They are sensitive when touched, but are not painful when I sit down. Do these symptoms sound familiar to anybody? Could they be caused by prolong periods of sitting, which I have endured occasionally lately? Please respond if you can help, I would deeply appreciate it.
