My 16 year old son had a ganglion cyst on his wrist that was painful. He put frankincense essential oil on it (undiluted) and overnight his pain had improved. Because he was no longer bothered by it, he didn't keep at it, so it is still there, but reduced in size. Another time it bothered him again and the same remedy worked for him. Frankincense essential oil is expensive, but useful for many things and worth having a bottle around. And it is cheaper than the doctor for sure!
