What is ThermaCare?
ThermaCare is an air-activated heat wrap using real heat that penetrates deeply to soothe and relax tight muscles. It gives 8 hours of relief while you wear it. And the long-lasting relief continues even after you take it off. Apply it right where you hurt for temporary relief of minor muscular and joint aches and pains associated with overexertion, strains, sprains and arthritis; and for minor menstrual cramp pain and associated back aches.
