HI, Inpain, and welcome! You have come to a good place. We have wonderful members that love helping one another and, as a bonus, we really do care about one another.
The chest pain can be quite frightening. I had that along with heart palpitations. My doctor ran many tests to rule out heart problems. It turned out to be fibro and costochondritis, too. At least now I know what is going on!
I see that Crazykitty directed you to the Fibro 101 thread. It's the first thread on the forum. There are links to a lot of good information about fibromyalgia and you will learn a lot there. There is a link all about costochondritis there, too. I think you just may see yourself there!
Be sure to keep moving with fibro. If you sit or lay too much, you will be stiff as a board. There are some gentle stretching exercises in Fibro 101 that really do help. Also, find a gentle exercise you like to do. I walk and I swim. Both are very good for the pain and they help keep your muscles moving and flexible.
I'm so glad you found us and joined in. Don't hesitate to ask questions because we are here to help you. Read back posts, too. There is a world of information in them. Meanwhile, I hope to hear more from you soon.
