Sometimes I feel dizzy and hands and chest and face go numb with tingling, my doctors seem to think it is a form of anxiety from hyperventilation. I don't feel it's the cause because sometimes it just happens. Mostly after drinking, or lifting weights. Makes me not want to go anywhere or do anything. Because I never know what to expect. What are some of your thoughts? Sometimes feel weak, or very anxious nervous, like an adrenalin or something attacking my nervous system. Once I hyperventilated and cramped up and couldn't do much and my fingers bent back. That time my hole body was taken over by massive tingling. I do have bad arthritis in my neck and back for a very strong 25 year old male. But this all keeps me from living with confidents most of the time, or from taking long drives.
