I know how you feel, I had surgery in July, and started having problems again almost immediately. Not sure if it's the CD or other problems from the medications I've been on. Unfortunatly, although we have hopes, surgery is no guarantee of remission.
Are you on any meds at all? Did your doctor put you on maintenance meds? Does your doctor know about
all these symptoms? Has he done any tests to find out what's going on?
If not, it's time to go back to your doctor (or another doctor if he doesn't listen), maybe get some tests, and see what's going on. If it's the CD, you want to jump on treatment as soon as possible, hopefully prevent another surgery. If it's not the CD, you want to know. Either way, a trip to your GI is in order.
