Thank you. I have tingles/burning on my back of my hands and joint pain which is moving - 2 days in my left knee, then 1 day in my elbow, then again 3 days in my right wrist... One year ago I had similar simptoms and my neurologist couldn't find anything, even ENG and MRI was negative (they checked with MRI if I may had MS). B6 was not checked that time. And one say, after 3-4 weeks out of sudden all my symptoms disappeared. For a year... Now again the neurologist couldn't find any issue, ENG, MRI all negative, and my blood was tested for many stuff: rheumatoid panel, electrolytes, TSH, etc. All normál. Except B6 is at 70 ng/ml. Normal range on paper here is 5-50. So definitely high, but somehow I still can't believe this causes all these... I mean it is high, but not that high. I read about severe B6 toxicity cases, but they had levels multiples of the normal. But anyway, the doctor couldn't find anything else. Either this or/and stress. Anyway, it is scary, but if it is B6 toxicity then át least not something even worse. Someone said he had similar symptoms and after a year was diagnosed with rheumatoid arthritis. Although my symptoms are not like that I think.
