TEHbAixwc: Many things can cause HA(headaches) .being dhredeatyd, lack of food, stress, a pinch nerve.I found that nothing helped me.I had severe HA and backaches for 2years. Seeing a chiropractor 2-3times a wk, taking too much Tylenol etc. Everything was a temporary fix. The pain would go away and then come back in a couple of hoursThen a friend told me about Himalayan Goji Juice. Drinking 4oz of juice a day my HA/backaches were gone in 2mos . I am firm believer in the Himalayan Goji Juice for any kind of pain!!!See site for more info
