Kandy, It is wonderful to hear your news. Yes, L-Glutamine is used by body builders not only for muscle mass but to aid in healing of injuries to muscles and tendons etc. I too was having improvement--the pain had really calmed down. I could even sleep all night! I ran out of the L-Glutemine for 2 days and had a terrible relapse. I could not find the original brand and started taking another brand, but after 18 days I'm still real bad. After reading your message I'm going to try to find my original brand again and give it another try. Wish we could email! I wish you continued improvement!
