I went to the dr today , thought i had a rectal prolaspe and i had a rectum exam and she said my rectum is good , so now i think i still have a prolas?

Second opinon : I think it's very likely that if you do have a rectal prolapse that your doctor would have noticed it upon her examination of you. What is it exactly that has you thinking you have a prolapse? If you want a second/specialist opinion, I would suggest a GI doctor or colorectal surgeon.

Thinking versus: Then your thinking is not valid or your perception is not correct. Since you did not share any specific symptoms with us we cannot comment further. But, a professional has examined you and verified that you do not have rectal prolapse.
