I have tried the castor oils packs, using a TDP mineral lamp as the heat source. It took the pain away while I was doing the packs, but as far as "long term" results, I cannot say I noted any in the two months I have been doing them----was doing 1-2 per day, usually every other day or so. Castor oil is also a GREAT product to use for wrinkles on the face---now it DOES work for that!
