I was given morphine a week ago in hospital (on waiting to have gallbladder removed) and since then ive been terribly constipated. 4 days since i started getting bum pain. It isnt the 'ring' area, its infront between anus and vagina. The muscle there feels incredibly sore. It started becoming uncomfortable to walk, stand, sit.. 7 days in now and Im in such pain and still no bowel movement. I went to out of hours this morning and was examined. No tears, piles etc. Dr seems to think pain is caused by the strain on my muscle. I have Never felt anything like it. Has anyone had similar? I am going to Florida in 4 days with hubby and kids and worried sick! The pain is so bad!
