I suffer from chronic pain and manage it on a daily basis. For clarity I have pain in my pelvis, back (broke my back), and knee. I was gifted this kit, and I am so grateful. All the components of this kit actually help to relieve pain. It has now become a family staple that both myself, my partner and my parents use. I suppose the best testament I can give to the efficacy of these products is that they can take me from a 10 out of 10 pain level to a 7. This is such a huge relief. To be incapacitated by pain and then be able to turn that into a more manageable level is very valuable. As an example, on a recent holiday to Paris I walked for days and hours on end, I never take taxis when I can walk, but at the end of several days on this trip I could no longer walk or stand upright due to pain and muscle seizing. I would run a bath and soak in the salts for 30 minutes and actually be able to move afterwards, followed with the spray, a massage and the roller, my body felt as good as it ever gets. I have used this kit to help others with neuropathic pain, muscle seizing, inflammatory responses from old injuries, and as a preventative precaution for injuries before activity that is known to cause flare ups. I would recommend this product to anyone that experiences disruptive pain, it is certainly a valuable addition to a pain management regime.
