Painful Knee Cap - Any Remedies?

I take Ibuprofen, rub some essential oil (Lemongrass, Bergamot, Black Cumin, Ginger and Frankincense, works really well for knees), and get a wet hot cloth to put on my knee and try to ride it out. Me personally, braces and tape never held in place and would slide around and make things more difficult. Building muscle in the legs can also help keep it in place, although that's hard when you have knee problems haha
