Chronic Pain - Nothing Is Working!

Hi! I'm a 25-year-old woman and I'm having a serious issue with pain.

I have been having pains in my chest area for years, but in the last nine months, its become severe. My doctor did X-Rays, MRIs, CT Scans, blood tests, and finally determined (3 months ago) that it wasn't shingles (which I have a history of) or a heart or lung problem - but that it is Carpal Tunnel. So she prescribed me a wrist brace and exercises to strengthen the area and help with pain.

Here's my problem - my insurance ran out two months ago and I am currently unemployed, so I'm completely broke. Several days ago my wrist began hurting tremendously, then it moved to my shoulder, and now it's in my chest. I can feel that the pain is not coming from around my heart, but appears to be coming from directly under my breast and on the left side of my sternum. If I breathe shallowly, I don't feel any pain, but if I breathe deeply or sit or lay in certain positions, the pain in unbearable. I can't even sneeze because I can expand my chest enough to allow the air in.

I have tried every over-the-counter pain medication, arnica, Icy Hot, Tiger Balm, hot pads, ice, baths, even my Tramadol prescription for when I first diagnosed... nothing works. I called my doctor's office and the nurse said that unless I come in for a visit (which I can't afford) there's nothing she can tell me. I'm in so much pain that I can't function normally.

Does anyone have any experience with this and any advice? I live in the Denver area and am desperate.

Thank you.

(By the way, I typed this with my non-carpal hand since I want to keep from using it as much as possible... I don't know if that's a good idea or not...)
