chronic diarrhea, nausea & joint pain

I am a kidney transplant recipient (over 10 years ago) who is relatively healthy. Started having nausea & diarrhea over the summer 2007, was hospitalized for dehydration and had many, many tests for all sorts of exotic causes, all tests, came back normal. Have had 3 colonoscopies 1 endoscopy, 1 small bowel xray, no resolution. Only found at one point elevated parathyroid, which has since gone to normal after short couse of Calcitriol. Dr. thought CellCept was causing diarrhea so they switched me to Myfortic (entereic coated version) I also take Prograf & Prednisone for immunosuppression. Post diarrhea, I get swollen joints with pain, mostly in my hands, some toe joint involvement and knee. This has been going on for months and I am at wits end. Anyone else experience anything similiar? I realize the transplant is a little challenging here but anyone who has experienced chronic diarrhea with or without the joint pain, your experience might be helpful. Thanks

I have this exact same problem! I haven't had an organ transplant. However, I've had the cronic (chronic) diarrhea, nausea, and joint pain (bad in both knees) on and off for about a year now. I've had both a colonoscopy and endoscopy and my small bowel xray is scheduled for a few weeks from now. June 5 I ended up in the hospital after my fever got up to 104 degrees F and the stomach pain and nausea got too bad.  I had elevated CRP levels (some protein in the blood which indicates infection) normal is 4.9-6.0, mine was over 110. They chalked it up to a colon infection caused by maybe stress or something. After a bout of antibiotics I was better. It came back exactly a month later and gave me the same antibiotics. The small bowl xray is scheduled for a few weeks from now...I don't think they will find anything again.. I don't know what I'm going to do if they can't figure this out. I can't keep living like this. Hope they figure yours out too. Best of luck.
