Started having low backpain July 3 Noticed "dead" spot on top of left foot. Foot started tingling, gradually going up leg. Continued having tingling which gradually included arm, mentioned it to friend who is doctor, he smiled and said it would go away after my sons wedding,(attributed it to stress)My son was married Aug. 19th, and still had symptoms.I figured I had pinched nerve in back, so I saw orthopaedist in Sept. He sent me for MRI, said I had "slight bulging disc, but was NOT pressing on any nerves. In mid-October,left side of face started feeling tingly and tight feeling, had "metallic" taste in mouth and felt "Big" tingly like I had been to dentist and novacaine was wearing off, have intermittent diminished or altered taste, drinks taste flat, food stale.Saw neurologist, after evaluation, I mentioned I had been bitten by tick in June, but he said Lyme was highly unlikely in Alabama.He sent me for MRI and blood work, "Solitary 1 mm hyperintense lesion in left frontal white matter.the inferior portion of medulla in midline has an area of increased signal on T2 weighted imaging, which is most likely vascular structure or artifact" blood test showed P41 Ab present, had elevated B-12 (1096) They called me in for lumbar puncture and more blood, while there, I asked Dr. about it, he said tests were basically to "rule things out" said MRI looked pretty good,said area on brainstem "has to be artifact" he seems very indifferent.Nurse called CSF normal, will call if he has further recommendations, very indifferent. Felt dizzy past few weeks.What could be causing symptoms?
