Although I'm not sure if I didn't overuse it recently, these attacks of weakness, tingling hands and legs are depressing lately.
E.g. Yesterday I felt a lot of tingling but not weakness, today, I'm weak, pins and needles in my hands and feet plus some tingling on the face. I don't feel any back pain though. According to my doc EKG is OK.
Still trying to figure out what is the reason of that.
