I have been using the Recovery Spray daily for over a week now and I have noticed a significant improvement on my calcify shoulder tendinitis. I tried all sorts of pain relief creams, sprays, salves, gels. They worked for a few days and felt it was just addressing the symptoms, not the root cause of the problem. I read up on the magnesium-calcium relationship in our bodies and true enough, the only time my shoulder muscles relaxed is after a magnesium spray or Epsom salt bath. Finally, on my way to recovery! Thank you so much.
