It is sad you have these life challenges. I several time had a chest pain not conected with the heart. I usual go to a chiropratctor and get a back adjustment. If it is effecting my breathing I get a large towel. Wet it and put in the microwave for no more than 20 seconds so I start a fire and place it on my chest and it seems to loosen the mucales of the chest and my breathing gets better. One of the good side effects that I see is it also losens the mucus in the lungs and removes them.
