Review on Sumifun Pain Relief Patch - Chinese Tiger Patches For Shoulder, Back, Knee & Muscle Pain (64 Count) by Laura Tolson

I generally use Salon Pas for occasional back pain and get some relief. I tried these and I was amazed. I was sleeping on an unsuitable bed and my back was bothering me. I put one of these on and within a half hour, I forgot I had back pain! There was still some stiffness, but exercise took care of that. I gave a couple to my mom, who had arthritis in her back. She was able to stand to straight again. She still had minor pain, but they worked better than anything else she had tried.Two things. There's a paper cover over the medicinal portion. Make sure you remove that or you'll be wearing this thing around for two days thinking they don't work. I wish there was some indication on the paper cover. If you've never tried them, it's an easy mistake to make. Also, they itch. I'm generally sensitive to adhesives, but it's mostly the medicine itself that itches. My mom had the same effect. I think it's worth it for the relief from back pain.
