i've been getting botox injections for about 12 years. first in the forehead but the last few years it's been also in the crows feet area. i started to experience light sensitivity a few years ago which has gotten progressively worse. i have the darkest non glare sunglasses available and i still have trouble with light. i also have times in the last year when later in the day i can't keep my eyes open. i have to force them open and several times i've walked into walls. i'm beginning to think it's from the botox especially the fact that i can't keep my eyes open. have some nerves been damaged? at this point i think i'm going to stop botox completely. i fear getting into an accident when i'm driving.
