This sounds like something my crew would have tried but used Vodka instead.My back was really hurting on a fishing trip and my buddy who was a Marine medic said let's try something. I had some sterile syringes that l used to inject air into worms and make float up off the bottom of the river so we stopped and bought some distilled water which he filled a syringe with and injected the distilled water into the nerve trigger points in my back at night and in the morning and at lunch. Crazy as it sounds the pain went away by the second morning and l finished the week up pain free. Never went on another fishing trip without my back survival package
