Hello @mia330, Welcome to Connect. I think I would also be nervous about any surgery procedure and want to make sure it's really necessary before having it done. You are asking the right questions and it sounds like you have a good action plan and a list of questions for your upcoming consultation. There is a website that has some useful tips for planning your conversation before going to an appointment that you might find helpful - https://patientrevolution.org/visit-tools. It has some cards you can print out and take with you so that you are prepared and won't forget to ask your questions.

Here's a little more information about the Gamma Knife procedure you may find helpful - Brain stereotactic radiosurgery: https://www.mayoclinic.org/tests-procedures/brain-stereotactic-radiosurgery/about/pac-20384679

@dandl48 has discussed trigeminal neuralgia in another discussion and may have some thoughts to share with you.
Can you let us know what you decide after your consultation later this month?
