I am a 49 year old female, I reached behind the car seat and hurt my shoulder months ago, I don t know if one has to do with the other, but for about three weeks now my joints in my hands have been hurting severly ,also my fingers, at night they go numb but when the feeling comes back it s not tingling its very painful, almost like my hands have lockjaw they will not not bend. If I use aspercream or warm water it helps but pain is getting worse. I can t grip or twist or even hardly open care door. Can you help me Lisa Donald
