Have been getting a very painful left trap about 20 miles into rides. When I sit up and drop my shoulders it is agony.

I have tried rolling my shoulders to try to relieve tension or angling my head but still hurts.

Has anyone dealt with this before? I am thinking of trying to rub some embrocation on it before a ride (does deep heat serve as a decent one) or getting a sports massage.

Might it be that i need to work on the muscle in the gym?
