OA Pain

I am hoping that someone out there has some clue of what I am going thru and can give me some advise.  I was so happy when I found this forum!  This is a bit of what I am experiencing:

I just had a TKR in February 2010 and am still having alot of pain and problems walking and weight bearing.  I had to have a scope on the other knee and they tell me that I will end up with a TKR for that knee also.  I am having pain in both of my shoulders and am scared that I will need surgery on them also.  

The surgeries have really taken a toll on me.  I am constantly in pain.  I have had to have injections in my back due to buldging disks since the TKR.  I ended up on anti-depressants since the surgery also.  I have missed so much work that now I am told that I can not miss any more or I will loose my job.

I am wondering if anyone else has had a TKR and ended up with more problems since the surgery?  Does anyone know if it is possible to have OA in all of  your major joints?   I almost feel like OA is taking over my body.  I am to the point where I go to work and come home and lay in bed trying to ease the pain from my legs and back.

I would love any imput that anyone could offer or even someone that has been thru this .....I would love someone to talk to via email or chat.  

Thanks for listening!
