Severe pain in right groin, pain walking and just moving leg and putting weight on it. X-ray shows no fracture. I have long term use of prednisone for arthritis. Ortho. doctor is sending me for MRI to see if it may be a vascular condition. I cannot remember exactly what it is called. But he said he has seen it before with patients on long term use of prednisone. Was wondering if you might know what this might be and how to spell it. He said this vascular condition will show the same symptoms. This is going into the fifth week of this. Has felt like a pelvic fracture, which I have had on the other side. Thanks.
