Had other tests, all normal-MRI+CT of head, EMG, blood tests for Lyme, Celiac, Myeloma, upper GI series, chest, back+left leg xrays, saw rheumatologist who suggested Fibromyalgia, neurologist who said could be B12, but didn't want LP or MRI of spine, and that B12 shouldn't cause such weight loss
, check for cancers. My dr thinks possibly MS, and
says wait and
repeat MRI in 3 mnths. Have only gained 2 lbs, still extremely faint when standing up, and still wake up with pain in left leg.
