What happened to my knee?????

hi guys. I'm a new post-er but a long time reader of this site. I started using CleanseSmart by RenewLife about a week ago and I've had good results with elimination. I'm also trying to do proper food combining, similar to Fit for Life, but without the fruit (because of a candida problem) ive noticed my knee flaring up and aching the past few days. every evening it seems worse than the evening before. its not really "painful" but more of a dull ache with some swelling. going up and down stairs is a killer, and its hard to avoid because i live in a multilevel townhouse, the kitchen on the main floor and the bathroom on the second floor. anyhow, does anyone think the knee problem and the cleanse are related at all? the real killer is that i took a job just over 2 months ago and my medical insurance policy isnt valid until June 16th! it would figure my knee would start bugging me 3 weeks before i have insurance, right? anyhow, hang in there, and thanks in advance for any replies.
