Wrapped my knees

My knees have been the source of pain for over 30 years 24x7... They have each had 2 surgeries and my left was bone on bone to the point that heavy activity can cause internal bleeding. Last night I wrapped them in Castor oil. They feel more comfortable today (and that in itself is saying a lot), but not much better in terms of function; range of motion, etc.

Should I expect to do this nightly for a long while? I am thinking so.
