A number of years ago, I had been running pharm grade gh for about 2 years when I developed carpal tunnel like syptoms in both hands that drove me nuts. Went to my ortho doc, who then sent me to a neurologist for electrical nerve response testing, Results were severe in the left and moderate to severe in the right, validating carpal tunnel. I didn't want surgery at the time, due to the protocol at the time was that recovery time was minimum of 6 months. My ortho doc told to try taking a vit B6 supp 3XD and possibly within 3-4 months "you may see some improvements". Thought it was BS, but tried it and it actually worked for me. It did reappear in the left hand after about 8 years. B6 didn't work this time and did have the surgery. Fortunately, protocols have changed and I was back lifting in less than 3 weeks. Take it for what it's worth, good luck!
