Have had numbness and tingling alternating on one side or other (arms and legs), loss of balance, some bladder incontinence, feel worse in hot weather. Went to neuro and had positive Romberg, positive heel-toe walk, slight weakness on left and hyperactive deep tendon reflexes. I was thinking MS but didn't mention it to neuro. He ordered MRI of head and spine (found out later it was on open .7T MRI). Brain MRi showed few "tiny punctate foci" in periventricular area, consistent with aging or small vessell disease. Spine showed cervical stenosis but not impinging on spinal cord. Return visit to neuro last week who said he had no idea what it is. I told him my eyes were now hurting, with sharp pain behind eye and he told me to go to an opthalmologist. My left leg now feels weak. He did brief neuro exam (none of the above tests) and said it was normal. I asked him if it could be MS, and he said, "No, it's not MS" I asked what it could be and he said it is a mystery and to return in 4 months. I am at a logg with the pins and needles becoming more frequent and fee like I am about to lose my mind. I am 65 years old, and I know that is awfully old to be diagnosed with MS, but have researched late-onet MS, so it is a possibility. Am I crazy for thinking that might be what it is. I am trying to get on with my life, but just don't know what to do. Thanks for any thoughts or words of advice.
