My left leg went dead in July. I am walking again but with difficulty, and I wear down real fast. I also have arthritis and diabetes since Jan. Went to a neurologist, first they said MRI of the brain showed lesions,it looked like MS, did a lumbarpuncture, then it wasn't MS,I should get EMG and 2 more MRI's and MRA. Medicare did not approve the MRI's and MRA, because the doctor did not show the need for it.. Now what? I can't get flu shot because I might have Guillane-Barre. I did have the EMG., no one from the neuro. clinic contacted me about the results. Very depressed. Has anyone else gone through this?
