My son is eight weeks past injury, complete t-10. About a month ago his right thigh swelled (while still in the hospital). This slowly continued until his whole right leg was swollen. Tests were negative for thrombosis, MRI (for ossification) and x-ray had no results. We were sent home with a vague guess that there was some tissue death in the muscles around his injury site (t-10) and that this was causing the swelling, by this time the whole leg was double the size of the other, with his thigh close to triple. The swelling began to subside, specially at night with ted-hose and elevation of leg. We were delighted. Now, in the last four days, though in the a.m. his ankle and calf look normal, he has developed a rock-hard lump in his thigh. This is not near any joint, it is mid-thigh, perhaps 6"by4"by2" thick, no heat or discoloration, no fever, all vitals normal, bowel program on track. Any experience with anything like this? Thoughts? Help!
