I have knee problems too....they are horrible, I just went to the dr recently for mine, it hurt to walk, stairs especially, I couldn't squat down at all with out having trouble getting back up. Dr said it was patellar tendonitis. Gave me asteroid that worked great and I put ice on my knees a few times a day. I found heat helps too sometimes. I'm not one for drs or medication. I also found walking and good stretching helps A LOT. I thought walking would be bothersome but once I got the initial pain to subside I found it helped some in that area. I would try ice and stretching for sure. Sounds dumb....but worth a try :)
