Hx,
BenGay and Activ-On are over the counter versions of Voltran Gel. Voltran has an analgesic in it as well as cayanne pepper. But you mentioned that heat does not help, and makes you nauseous... so these gels might not be good for you.
I personally like ice best. It took about 1-1/2 years for the burning pain from the pec minor releases to subside. But on days where I'm in bad pain, sometimes ice will help.
Hang in there girl - time may be the best healer of all.
