I had a knee injury at 16. Every once in a while my knees give me trouble, maybe or maybe not related to the injury. Anyway, last week my knee was really bothering me. I had pain under the kneecap and it was making me limp somewhat. I had not even done anything that I knew of to bother my knee.
I soaked a cloth (not dripping) with castor oil oil and wrapped my knee with it. I covered that with plastic wrap and covered that with an ace bandage. I slept with it that way with a heating pad. It was somewhat improved the next day and now my other knee was a little "twingy" too.
So for the next couple of nights I just massaged castor oil into each knee and loosely put a thin flannel baby blanket on my knees to protect bedclothes. I used a heating pad one night. But in a couple of days, all knee pain was gone in both knees. I have continued to do this each night anyway, just in case. The skin on my knees is very soft now, too!
