I experience arthritis like symptoms, my knees, elbows and finger joints are all prone to inflammation. I have been doing much better since having jpouch surgery but I also started using cannabis around the same time to help me put on weight. I still feel like an old man though and I'm only 35, but I worked hard labor for 17years part of the time struggling with UC. Prednisone also apparently has done a number in my body.
Good luck
