hi doctor my husband is 40 years old is quite thin always been like that. he has just finished a course of cleocin for a gum/teeth infection. he was in severe pain so was also on endone. he was also on 2 panadol and 2 neurefon every 4 hours. for approximately 4-5 days.the endone was almost every 4 hours for the 3 days. the pain has since gone he is no longer on any medication but now has stomach pain constantly and a sore anus and feels like he has to do bowel movements all the time but only a small amount of runny bowel movements comes out. any ideas would be great. Thank you
