Thanks so much to everyone for your replies and advice. Until I get some good answers, I will be staying away from surgery. Not only do I have severe osteoarthritis in my hip, but a bad bunion on my left foot that causes me terrible pain. It is hard to know is the pain is intensified by the rsd or just foot pain. I was able to put up with it in my rt foot for many years before having the bunion removed, but that was b4 rsd, I am still youngish and am concerned about my mobility in the future. I move as badly, or worse, than my folks who are 35 years older than me and have had replacements. Oh well, sorry to vent. Hope you all have a good evening and a pain free weekend. Hugs.
