I assume thousands of people must ask this. After looking at several dozen sites and reading many descriptions of hemroids, I do believe I have one but it seems to be too high.
It is at the base of my tail bone, At the very begining of the cleavage formed by the buttcks. It is an inch in length and reaches from butt cheek to butt cheek. There was what seemed like a small zit on it. This popped and I had experienced a large amount of puss oozing out followed by blood.
At first I thought I had minor bruising on my tailbone, I passed out on the couch and sat between the cushions onto the hard frame. I had a bruise by my tailbone for a while before it then began swelling, as I have described. I assume it is a hemroid, but figured I would ask around first.
