I had one many, many years ago. Saw an Osteopath physician. He lanced it, and put a wick in it. It drained. He took the wick out and it never came back. No more problems.
I think he may have given me anti-biotics too.
All of the cleanses will help. The parasite cleanse will get rid of the little critters that are making the cyst. The liver cleanse and kidney cleanse will help strengthen your immune system, so the can't come back. I have been cleansing for many years.
