I have terrible cramping in my feet and legs due to side effects from statin drugs, that I no longer take. My feet have also been broken and hurt all the time. When I use this at night it keeps my feet from cramping and seems to help me sleep so much better. I also use it when I pull a muscle or over do it and feel that twinge in my back. I'm 59 years old and have been very hard on my body, this deep tissue salve helps me manage my pain. I cannot take otc pain medications, nsaids and such make my heart race, I'm trying to rid my life of chemicals and this is game changer. It helps me, with no side effects! Combine it with a heating pad and I wake up feeling great. I have shared it with my friends and family and they are also mazed at the results. A little goes a long way and a jar will last me several months. I'm so thankful to have found this product!
