This isn't a cure, but it is close. I am a massage therapist and my specialty is deep tissue massage. Been doing this since 1980, so my joints were getting pretty well beat up. I tried all the usual remedies but they didn't work. I got turned on to the following:
1G of food grade sulfur along with 500mg of Vit C. I take this combo 6-8/day.
Sulfur has many benefits for the body. I no longer wake up with stiff joints.
