Just thinking after reading your post several times I too suggest a 2nd opinion. I saw that you are sitting all day at a desk job. I don't know how many years you have been doing this, but your body conforms with your work and vicversa. You said you are no longer as active. I too would talk to the doc about physical therapy and some ways to relieve your body from stressful positions. I know for me sitting with the computer for too long and then barely get up. I do pool exercises at our local physical therapy building and it helps. I hope you can find relief. The anxiety also works against your muscles making them tight and painful. My best to you.
