I cannot believe how this product worked on my spine. I have degenerative discs and just recently had a mastectomy with reconstruction and I tell you just trying the sample I received of Joint Medic has me sold! I can finally stop taking pain relievers(Percocet) which really was not working on my pain and also having fear of getting addicted. I will sing your praises from the roof tops to everyone I know! God bless you this product is amazing!
