About the middle of my second week I started feeling knee pain, and has not gotten any better. The main reason I began taking the HALO was to jump start my training for a 5k obstacle course over labor day weekend, but now because of my knee pain I cannot run. I have been taking in between 1 and 1 1/2 gallons of water each day. I also take glucosamine/chondroiton supplementation currently osteo biflex. Any remedies to cure this quickly would be much appreciated, I am plenty strong for the obstacle course but need to run. I just ordered a 2nd bottle of HALO because I planned on upping to 75 mg ED.
