I read an other with the same problem as all the others and nobody to help relieve your pain. This must be the dark ages or what.
Are you one to wear underwire and push-up bras, well they are known to cause pain too. You should be wearing the full cup size type bras and no underwire.
From what I read, you certainly have pinched and dislocated nerves in your mid & upper back areas and they must be rest soonest. Otherwise it may get worse.
