My husband had 5 blood transfusions. He was down to 5.6 hemoglobin??. He was released from the hospital yesterday. Now his left arm is experiencing major charlie horse type of pain and his lower arm and hand are swelling. Do we need to be concerned? In November he was hit by a truck (he was a pedestrian). Taken to Emergency room to x-ray for broken bones - none. Apparently, though, since he was on blood thinners, he did experience internal bleeding. A scope both down and up his body this Tuesday showed no sign of bleeding, ulcers or whatever.
