Hip Replacement

Thanks for the hope.
I had my RNY in February, 2005.  I exercised and learned to love it!  Walking then jogging (I like to think I run) and spinning.  I did the Susan Komen run 3 times!!! Going to the gym became very important and a large focus of my life.
And then the pain started in my right hip / leg about August or September this year, but it took me till December to get an xray. The XRay tech said it was a sports injury; no fun, but, it would be the 2nd one on that same side so I thought not a biggie, I'll do the therapy and back with my life the way it was shortly............. But my GP said to get an opinion from the orthopedist - SURPRISE - he recommends a hip replacement!  He also xrayed my shoulder for me and sure enough he said exercises are needed to ward off frozen shoulder.
What the hey, could this really be? And all at one time too?  I am in denial,  wanting a 2nd opinion and to understand why:  I think I did the right things, lost 100lbs, did the exercises, etc.. and now this is happening? I'm only 60 and this has really set me back on my butt. Reading your stories though has been encouraging.
I'm not sure how this will turn out as I haven't gotten that 2nd opinion yet and have insurance for the surgery, but don't know if the disability will be enough.
I'm scared - but thanks again for the hope. Updates on your progress would be great and much appreciated.
