Bizi, I am a mess! I have pain everywhere

I have had a gait disorder for 9 years, and it's hard on my body. The more active I am, going out all the time for appointments etc, the worse problems with my hips and knees get. I think it's arthritis.
Things like that usually fall down pretty low on my list of complaints aside from the times when they really flare up.
I've already gained back the 4 pounds I lost. It happened fast. I was determined to watch my weight better, but I haven't exactly been cooking light, and then I had Chinese food last night. I think I'm using too much salt. That can't help. I am not happy with my weight.
