I have a friend who developed a HUGE ganglion on her wrist. She had another ganglion removed before, from her other wrist, at great medical cost. She even had to fight to have the doctors do it with local anesthetics and not put her under completely.
I told her about my ganglion that shrunk after I started rubbing Castor oil on my foot - not specifically for that reason, just to remove the excess oil from my hands after applying it elsewhere. One day I just noticed the ganglion was gone, and it had to be the Castor oil.
I did not see her for about 2 months, and yesterday, she showed me her wrist - BUMP GONE!
