Or I guess you can do an adjustment to what I did with the castor oil. And put the oils on your butt, then put a heating pad down on your bed, lay a sheet of plastic wrap over the heating pad (just to avoid getting it all oily), then put either a wool cloth (they sell them at the health food stores too), or a baby burp cloth over the plastic wrap (make sure it covers the plasic wrap completely to avoid the plastic from touching your skin) and lay on top of it. Don't make it too hot though, I think low heat should be fine since your body weight will be pushing against it. And really, you can lose the heating pad after about 10-15 min.

The heating pad just adds circulation in your butt (which is good!) and with castor oil anyway, it helped the oil penetrate deeper.
