starting on Sunday, I have been having very severe anal spasms along with a ton of pain, and some itching. It is very hard to sleep at night due to the pain. I have not been constipated, so I don't think it would be hemmorroids. It does not hurt to go to the bathroom either. The pain is pretty constant with spasms very often, and when I have a spasm the pain is so intense that it causes my entire body to tremble. I would describe the pain as almost like a bite near my butthole. Nothing I have tried has given me any relief. I have googled my symptoms and the only thing I have found that sounds somewhat simliar is an anal fissure, chron's, or colon cancer. I called a doctor's office today and spoke with a doctor and he said that I should not be worried and it's more than likely a fissure. Can somebody please help. I want to know that it's nothing extreme. Thanks.
