Am a 21yr old male. 3 months ago developed numbness in the ball of my right foot. It remained the same for the next month but then occurred over my entire right foot. It was completely numb and began to burn. My doctor thought it was a torn nerve and gave Naproxen. It didn't help and the entire right leg up till my knee soon went numb. X-ray of right foot was negative. Given vitamin shot but didn't help. Blood tests ruled out diabetes, gout, cholesterol problems, and showed no signs of infection. Doctor gave me Gabapentin for burning and tingling. That helped a little, but I soon had a feeling of numbness on the right side of my head from my ear all the way back. Taken off Gabapentin. Went through CT scan which suggested an enlarged area in my left parietal lobe. However, an MRI ruled that out. Meanwhile my entire right leg grew numb, as did the tips of my pinky, index finger, and thumb on my right arm. CT arteriogram, and MRIs of the thoracic and cervical spine ruled out aneurysms, stroke, MS, blood vessel malformation, vasculitis. No other abnormalities seen that could cause my symptoms. Neurologist used tuning fork and cotton swab to test the numbness. During this time my whole right leg was numb, burning, and stiff. lood tests were normal for sedimentation rate, rheumatoid factor, Hb A1C, B12, TSH, ANA, DNA DS Antibodies, Lyme disease, Sjogren's ABs, no cryoglobulin, non-reactive RPR, and no heavy metals. Back on Gabapentin to reduce burning. Entire leg, fingers, and head on right side constantly numb, leg stiff. Not a stress problem! Any thoughts? Further tests?
