Hip replacement? Cortisone shots? [View all]

Back in January and February I fell on the ice - hard - and I jammed my hip. The trauma cut off the blood supply to the femoral head and I have avascular necrosis. The femoral head is disintegrating. I have to have a hip replacement, no ifs ands or buts.

This morning I got a cortisone shot in my hip. I cannot believe I immediately feel so much better. I'll get the hip replacement this fall. When the cortisone wears off I'll be miserable again.

Has anyone gone through this and can anybody tell me how long the relief from the shot lasts?

Thanks in advance.
