Andy, I delayed for several reasons...first, the idea of any surgery is not tops on my list (maybe liposuction?) Anyway, tried all the lesser evils first: massage, chiro, PT (2 months), manipulation and release therapy, steroid injections, horsepill ibuprofen. None provided relief past a few weeks or at all, and eventually the inability to walk without limping and sometimes falling, and the inability to even sleep for more than an hour at a time forced me into action.
I felt so bad and miserable that I would NOT have hesitated to have a THR if that was all that I could get to stop the pain and regain my life. Luckily, like many here, I wanted the added benefits of a return to full activity that the HR promised. By the time of the surgery, though, I would have placed the future activity far below the need to be pain free and just have a normal walking, sleeping life.
Knowing where I am now, I would have loved to get it a year earlier. As it was, I felt blessed to move into a cacellation a month and a half early. The biggest problem for me was the speed of the decline in my life. I went from feeling tightness in the front of my hip after a road race, to having spasms in the piriformis area of my butt to being mostly crippled and in pain within 6-8 months. Not a lot of time to get diagnosed, get bad information from orthos, chase the tail of lesser fixes, and find a surgeon to perform the HR. But here I am, happy and hippy.
So, Andy. If the xrays and the doctors say you can benefit from HR, I would probaby not delay getting the surgery while you feel OK. Its probaby only temporary. But it is a BIG decision and you should want to feel and sure and comfortable as you can.
