Heat therapy products can go a long way in relieving your back pain.  Heat allows more blood to flow to the affected area as it expands the blood vessels.  Heat can be applied by using a moist towel that has been heated in the microwave or by using a heating pad. 

 One of the best things I’ve ever found are Therma-Care HeatWraps which are air activated and can provide powerful pain relief.  The best thing about these HeatWraps are that they are portable–no extension chord needed!
