I was reminded of the big reason I have started dieting and it was because of my knees. I did not know if I was going to have to have surgery on them. or what I was going to have to do but they were getting bad before I lost this 14 pounds. So I wish you luck with your delimma and remember, this too shall pass. Whatever you do I know you will work it out and if you can just keep from putting the lost weight back on you will have acomplished a lot. good luck.
