I was diagnosed with colitis, currently have a jpouch, also diagnosed with ancylosing spondylitis, I also have brain lesions. My neurologist has been monitoring the brain lesions for some time, 3 months ago did a spinal tap,and said I had ms, put me on aubagio. I have no other neurological symptoms of ms other than the lesions. when I asked why spinal tap confirmed ms he said it showed inflammation in my body, but I have two inflammatory diseases, so would this be a confirmation of ms? I have been on aubagio for 3 mths and I am having a hard time gripping things, finger tips numb and tingly and have numb patch on my side. went to hospital and they said it was a ms attack. How can it be an attack when i have never had symptoms before meds and now I am on meds to control attacks and I have one? I think it is a reaction to the meds, but they disagree. I am questioning my ms diagnosis, is there any evidence that could support that AS could cause the lesions, any thing else we should be looking into? or is ms a proper diagnosis? any advice would be greatly appreciated.
