I so understand your pain. I am having problems right now with it. It does come and go and so far has only lasted a few weeks at a time. But right now it is so sore I have a hard time wearing my bra ( sorry guys). I also get that breathless feeling alot lately too. So far nothing really helps, I put the heating pad on and used bio freeze/ tiger balm ( not at the same time

) and it only helps a short while. Also hot showers in the morning helps loosen things up alittle also. So far nothing has gotten rid of it completely...Sorry I am not much help but I know how you feel believe me...
