Hi C.,
I am 33 and get ganglion cysts on my wrist a few times a year. In fact, I had one last week. They can be a bit painful but not too bad and they will go away on their own. I swear I am not a crazy person but I too had heard about hitting them with a bible (or other big book) and decided to try it. Believe it or not, it went away almost immediately. I would certainly NOT recommend this for a child but this old remedy does work. Just last week my husband had the pleasure of hitting my wrist with a big cookbook and it was gone in a few hours. AGain, please don't do this to your daughter but perhaps if it continues to bother her as an adult she can make that choice herself. Otherwise, I say just let them go on their own.
