Questions about different procedures

Hello,all! Been a while since I posted anything but this time I have questions about various procedures in which I may be enduring this next month. So...Here goes! Thanks for any and all advice!

Balloon Compression:

1) Has anyone had it to try and treat the V1 nerve? If so, did it work?

2) What side effects have you experienced?

3) Has it helped anyone after a MVD surgery?

Gamma Knife Radiation:

1) Is it worth it?

2) Have you had it done on a V1 nerve?

3) Do the side effects out-weigh the benefits?

4) Is it true it can cause more pain than good?

2nd MVD surgery:

1)What lead your Dr. to believe that you needed it?

2) What was found and how was it corrected?

3) Would a 2nd MVD be beneficial to someone who has had the surgery about 8 weeks ago and what might be the risks?

Cutting the V1 nerve:

1) Are the side effects worth the drastic surgery?

2) Does it work?
