I had my GK on 4/3, and 10 days later, no scars whatsoever. It probably does have to do also with your skin... my skin heals very fast. In fact, if I get a pimple (at 42 years old LOL) it heals after the next day. Whereas my wife, hers ends up in a scar for months!!!!
I would like to say that the most important aspect is to do the cold compresses for at least 48 hours after GK. I did it for 72 hours, even pretty much slept upright. I can say I have NOT had any headaches post GK. In fact, I sometimes think my GK was a scam.. that I was put into a machine that just made some clicking sounds.
But yeah, I did feel some pain deep inside where I believe my tumor is, a week after my GK... not the same as prior to GK where I had migranes and headaches. But that deep pain has since went away.
I am waiting patiently for my first post GK follow up. The doctor wanted me to come back in 2 months instead of 3 which makes me a bit worried, but he has assured me I won't die from AN, instead from something else... I trust my dr (Dr Duma) 100%
The important thing is even after my hearing loss, balance issues and tinnitus, my wife still thinks I am a 9.9 out of 10
and that's all that matters!
