I was diagnosed with Fibro about 5 years ago, but have been suffering for about 8 years. My muscles in my upper back hurt all the time. It is a deep burning pain. When I am having a bad flare up, they hurt so bad. They get so sore, I feel sometimes they affect my breathing. The muscles around my chest cavity get so tight that everything hurts, and I feel like I cant get to the top of my breath. This is a hard sensation to describe, but I was wondering if anyone else could relate to this? I was also wondering if severe muscle tension in that area could actually cause that sensation? Thanks in advance to anyone who can share or help.
