Oh yes you can, I ve been diagnosed with fibromyalgia and rheumatoid arthritis, lately I ve been suffering severely with feet problems, I tried compression stocks which seemed to make it worse, I have these types of nodule, red bumps on my ankles that burn like crazy. I had an unusual morning with my right foot, my big toe felt like electricity was flowing from my big toes all the way up my leg, its scaring the heck out of me. I used my ThEn.S on them which helped a tiny bit. I don t know what to do anymore
