Tuesday I went to the doctor because I've been having issues with my hands. Number, pain and cramping. My thumb goes inward . The past months I've literally feel weak. I try drinking an energy drink just to get me a boost but nothing. I do take multivitamin and also b12. That doesn't help me. I even try the thrive product that has all the vitamins which still doesn't help me. I can sleep and sleep and still feel week. I'm having a hard time at work because of it.
