Currie, don't ever stop Prednisone cold turkey without consulting your doctor! Even when I've been on just 10 mg for a short period, I have to taper 2.5 mg / week.
Kit, thanks for the PT info. I will ask my doctor about it because I think it might help. I have a lot of pain in my right knee, and my left leg is much weaker than my right leg, so I suspect I am overcompensating with the right leg (especially on stairs), and overusing/tiring out my right knee. It feels to me like if I could strengthen my left leg through PT it might help cut the pain on my right knee.
Isabelle and Currie re: abdominal pain: Currie, I'm not sure if you are a woman but if you are, do you notice any association of pain with your menstrual cycles? I had excruciating abdominal pain when I was younger, and it turned out I had endometrial tissue adhered to my colon and wrapped all around it. (My gynecologist discovered this during a laparoscopy to remove fibroids.) Depending on where I was in my menstrual cycle, it would swell and squeeze my colon causing severe Crohns-like pain and diarrhea. I ended up having a complete hysterectomy when I was 35 and the pain went away completely. Now when I have abdominal pain and / or diarrhea, I know it's Crohns. Luckily I don't have it nearly as often. It was a hard decision to make to have a hysterectomy so young, but I am so glad I did it. It has made life with Crohns much more bearable. There is more discussion of this issue in the Women Only section of the Forum where menstrual cycles, pregnancy, hysterectomies, etc are discussed. (I guess these subjects skeeve men or something.)
