Have you been tested for Gout? I found out that is my main joint problems, I thought gout only affected the feet, but it's all joints!

Yes. It was explained to me by my rheumatology doc the as the spine is anklosing,
It can feel like chest pressure or shortness of breath due to the spine being less flexible. It helped me not be so fear full of the sensations.

Yes omg my joints hurt so bad I shouldn't be holding the phone but cant sleep as usual and breathing had chest xray yesterday going for breathing test next week I didnt know my spine had anything to do with my breathing problems but about 2 yrs ago I was diagnosed with copd. Im going to see my rehumatoligst this morning hopefully getting infusions of some kind.

Yes! Both of my knees, now starting in my shoulders. Waiting to start ivig therapy. Praying this helps. It is horrible. Some days my knees are so bad, i can't fubction at all.

I didn't know that problems with the spine could affect the breathing, I have asthma and COPD, I also sometimes get pain around my ribs, like a crushing feeling as if you have been hugged too tightly. So I can see why it might affect your breathing.
