I'm the one with the shoulder injured by the Physical Therapy evaluation. I went for an MRI Tuesday. The technician had me lay on my back, and she positioned my arm just so, then asked me to hook my thumbs in the waistband of my pants to help hold my arms still for the 45 mins. of the test. She said, oh, my, why are your hands different colors? HUH????? Yep, my hand (and arm) on the side with the bad shoulder is sort of bright red, like it is sunburnt. It is several shades redder than my other arm. (My skin is normally pink/red toned anyway- but not this red!) The other hand is normal. I have no idea if it's been that way since the shoulder injury. I don't often hold my hands together and compare them. But - it's been that way at all hours of the day and night since Tuesday morning. When my Dr. called with MRI results Tuesday evening, I told her about it. She was a bit alarmed, and scheduled me right away Wens. morning for testing on that arm to be sure there were no blood clots. There were not. The MRI said I have severe tendonitis in the shoulder, and looks like a pinched nerve (but I have no numbness, and no more tingling than I usually do)... and what looks like a tear in one of the tendons, plus a dark area that they think might be pooled blood from some hemoraging in the joint. She's sending me to a shoulder specialist. [And, the physical therapy evaluator said "there is no way my evaluation could have caused you any physical damage] I've searched all over the net, but can't find any reason for my hand/arm to be red. Some sites said about hands becoming pale or blue but nothing about red. I know that this shoulder is VERY painful..... not just the joint, but going down halfway to my elbow it hurts A LOT, and also the muscle going over my left breast, and the one going around my back, over my shoulder blade. It's been about 6 weeks now since the injury. My shoulder, arm, hand and upper back on that side, are all slightly swollen. Anyone ever hear of this before???
