i am having pretty sever pain in the anal area. I have had haemorrhoids before, and at first i thought that was what was again, but then it got worse. it hurts all of the time. The pain never goes away, bowel movement are excruciating, there seems to be a lump similar to a hemmeroid, as well as pressure on the left side just up from the rectum. I have been using tucks wipes and preparation h, but nothing seems to be helping. what could be causing this?
