I used heat, spas, massage but the pain returned a day or two later. She has a running appointment with our Rolfer to get a tune-up every six months. I recommend it for everyone. It even addressed those minor muscle pains inherent in the body that I'd ignored. Now they are no longer troubling me.
Muscles endure repetitive strain.
A simple injury, with a suitcase can develop into a shoulder cramp, the muscle shortens from strain. Rolfing returns you to your optimum and balances your body.

It helps me with downhill and cross country skiing, and bicycling which require balance.
