I am about 18 months post surgery and a year post CK, and i get still get twitching from time to time. I also get random numbness around my eye, and if i suck on a straw i can make it twitch (if i am stressed).
The months before my surgery, I had issues with my eye. It was ultra sensitive and the eye lid would swell up if I used a different type of soap, and the skin would get very dry. I went to the eye dr and fainted (hit the ground and they took me to the Emerg Dept) so something somewhere was happening, but it is just twitching now. I never had a good explanation, but it was only happening on the tumor side eye, which tells me something.
My dr said it is most likely the nerve getting irritated, its a tight space in there.
+1 on staying safe.
