Hi, I am male 22 year old. Experiencing burning and tingling in my hands, forearms, feet and in a small around around my lips and jaw. I did have a head aches with similar symptoms but that has almost completely gone away. I was taking vitamin b supplements without consulting a doctor for about 3 1/2 weeks. Up to 36 mg of vitamin b6 and 140 mg of vitamin b3. I stopped taking these 5 days ago. I visited the E.R and they said the excess vitamins would be removed through urine. I am wondering if these symptoms are temporary or if i have possibly caused permanent damage to myself?
