. To find out if this is the problem, you'll have to have a MRI. This will let you know. If you are getting shape pain that comes and goes, depending on activity, there is a good chance you have torn some cartilage. If this is the case, you will want to get it scoped. It's a very easy surgery to have and you will be back on your feet the same day, or next. It's amazing the work they can do with knees now days. I have had several knee opps and now my knees never bother me while squating. 

If it isn't a tear of some type, you can use some fish oil at 3-9 grams a day. This will help with inflamation and kind of "lube" your knees. Glucosamine may also give you some help.
