Free text: After 1st shot, from next day, I've weakness in my hands. I can't sometimes make strong fists. It feels funny and I can't control it. It's not by the elbow but by the base of the fingers/joints of both hands. I have to massage the area and/or pump the fists in order to gain strength. When I wake up, I lean against the wall with the fists and do few push ups to gain strength. I can't fully grasp the phone in my bed to text someone. I have to do it with my finger one character at a time. It feels like the phone will fall. After the shower and little massage, it feels normal. It happens many times during the day but it has not affected me in such a way that it would influence my job. But I am concerned. I read a lot online but none of the symptoms match to mine. Please suggest.
