I have fibromyalgia and chronic migraines, so a friend gave me your M & J Salve. I had a headache and my neck and shoulders have been hurting, so I decided to try the M & J Salve. At first I just used it on my temples but then I decided to rub it on everywhere that hurt! I felt it tingling after I put it on and (it smells great) then I went to bed. I woke up and was going about my day when I realized I wasn’t in pain! I have been suffering with this pain for weeks! I’ve been using it every night since, and it has greatly reduced my headaches and pain and best of all my neck pain went away.
