Outside of both knees really hurt at night while sleeping on my side. Doesn't hurt all the time at night, but is getting progressively worse. I exercise 2-3 times a week and have lost weight. I am not a big fatty. I also have pain in my hips. Not sure if bursitis. The pain wakes me up at night now. Going to try ice tonight. Have tried ibuprofen, but not much. I don't like pills unless I have to. Any ideas? The internet says some kind of IT band irritation might be the cause. I have not seen anyone about this yet. Don't even know what kind of professional to see.
