Thanks. I have an arthritic hip. If I don't do much more than ride the bike, swim and do pushups/pullups its ok always a little discomfort , but OK. Any lunging or squatting below about 45 degrees hurts. I can't run and forget about any kicking or take down work. Even boxing with the pivoting causes pain the next day. The ortho advised me to just stop doing anyhting that aggravtes it and postpone surgery unitl the pain gets to be too much. Like I said , if I don't do much its ok. I was hoping she would say," get a new hip and you'll be as good as new, running , kicking , jumping etc..." but i guess thats not the way it goes. I just turned 60 and have some decisions to make, but man I would love to be able to run again. Anyway, thanks for the update.
