One year ago, I slowly developed whole body tingling, memory challenges, high heart beats, taste problem, low cognition, rapid hair loss, joint pain, hand and feet pain, heaviness and pain in head. I had been going through severe stress for few years now. I was diagnosed with B12 (122) and D3 deficiency, fatty liver 1/2, triglycerides high, a bit of abnormal cholesterol. NCS was normal. Had seen physicians and neurologist. Had some relief but never normal and fresh. Now my B12 is rather high. Have same symptoms (-taste problem, + strained eyes and occasional balance issue). Tingling is high when waking up and when thinking or stressed and remains all the time. I live alone and feel like my mental state has got stuck.
