Hubby is on 6 mth tour for 3 weeks he has had pins and needles in right lower arm and hand, from elbow up to neck he has severe pain. Spent week in Hospital doing different tests all clear. Problem is physio gave him exercises for his neck and said not touching arm as we don't know what is wrong and thats it. He isn't doing his job as he cannot use the keyboard and they have now cut back on his pain relief as they want to see if the physio for neck is working. People have said he should of been sent back to Germany/Uk to sort this out. If Dr doesn't suggest this what can he do it really is getting him down he has very little sleep and they did knock him out with an injection on Sat night. UPDATE. They are sending him back.
