I had TKR Wed. Jan 27. Today is Feb 2. I'd not had a bowel movement yet. The doctor sent me home with a script for colace. Nothing! I called the doc back and the nurse told me to get some Miralax and some Senakot. So far (2days) still nothing. What do you think I should do? I certainly don't want another painful problem.
