I had a painful cyst under my breast that finally got to a point that I really needed to do something about it, even if it meant going to the doctor. It was purple, abscessed and about the size of a small trawberry. Tea Tree oil was not working at all. Well, I don't like doctors and would be prescribed Antibiotics anyway, so I got desperate and did some searching. I found the R message in which castor oil was recommended. I had my husband get some castor oil. I googled castor oil and found that it works really well with Iodine mixed with it. The combination is great. I applied it every couple of hours and started at 9:00 on a Friday night, and by 2:00 the next day the cyst had drained a lot of fluid. It was so frustrating having the cyst because I could feel the fluid underneath the skin, and I could feel it growing, but I couldn't get to it by squeezing. It felt great to have the cyst drain on its own (with the help of castor oil of course). I highly recommend castor oil. It worked for me also.
