Hi - I had surgery on Thursday (4 days ago), and have not had a bowel movement since then. I am usually very regular (2 times a day). I am taking Percoset for pain. I was on stool softeners to help, but ran out last night. I have not been eating as much as I normally do - most days only one meal (as opposed to three). I have tried a saline enema (twice) with no results - very, very little stool was present. I have not had the urge to defecate. I pass gas regularly. If I push as though I am trying to defecate, I usually either get the urge to urinate, or produce gas. How concerned should I be, and what additional steps can I take?
