I have suffered from Crohn's for 21 years. I have an odd question, I am experiencing a vibrating sensation in the lower spine, with a fever, and cramping towards the middle and left side of my belly, and some diahrrea. I am heading to the doctor tomorrow, but was curious if anyone heard of such symptoms. I also take coumadin to prevent blood clots (I had a previous PE) and my PT INR was high, so coumadin was halted until I am seen tomorrow. All strange symptoms and all things I have not experienced before!
