Hi. I had Gamma Knife this past March. The only thing that I didn’t like (which I was knocked out for) they installed a metal halo to my head. I had 2 screws in the front of my skull and 2 in the back of my skull. They use the halo to lock your head in place so it doesn’t move during the procedure. I was semi conscious during the procedure, no pain or anything. Taking out the screws was easy. I had to keep my pin holes clean until they healed. I have scar tissue where the pin holes were. No complications. I get my 6 month check up in September. It’s amazing I was there for 6 hours, then went home. Here’s hoping my next MRI reveals only good progress. 🤞🏻
