Hi Hutch,
Yes, I am glad I had surgery, it was a while ago now, but I'm glad my Neurosurgeon decided to operate at the time.
When some Doctors say that the cysts cause no symptoms or other neurological problems...they are usually wrong! It's often difficult to find someone who agrees that cysts cause problems in some people. You need to find a Neurologist or, preferably a Neurosurgeon who will take you seriously when you have a large cyst causing problems.
