Possible cyst: I think you already know what I am going to recommend. If these methods have not helped, it is time for a medical evaluation. Take care.

Basics: A ganglion cyst is an accumulation of material encased in a membrane surrounding a nerve. It is not a simple swelling that might respond to heat or immobilization. Treatment usually requires decompressing the cyst, which can be done in the office. Many just ignore them unless they interfere with function or cause pain.
