I would try the kidney cleanse in your case also. I'm getting ready to start it again this weekend, and have done it twice before. Do the entire three weeks, and follow the instructions. It's not very expensive, especially for a three week program. Dr.Clark used to sell a kit form, but has changed the format to individual products so you don't end up with so much leftover of some products.
Did you have an accident/injury to your hip, lower back, and/or knee?........a fall, car accident, anything like that? I don't want to get into a detail of analysis in the forum, but would like to help if I can.
