My pupils have been unusually small since the concussion.

On the days that I feel better than usual, my pupils appear semi-normal. On really bad days, they are very tiny.

My pupils do get bigger in the dark (I have checked by covering my eyes and then removing my hand), and the sizes are not uneven.

Everything that I've read online seems to say that pupils should get bigger, not smaller, during a concussion. Can small pupils be caused by a concussion, and if so, is there anything that I can do to fix it?

I don't have vision insurance, but I have an appointment with the eye doctor in early February because my vision has gotten very bad since the concussion. I'm curious if there are any special tests that I should request while I'm there or if rest, eating healthy, etc. will help my pupils become normal over time.

I would like to ask a quick question... do you use opiates for pain?
Or smoke, or use the nicotine patches/gum chronically?

Most drugs dilate pupils, but a few constrict, and sometimes the constriction is a short time period after using.

I do not smoke anymore (quit years ago), and I do not take pain pills. I used to take Xanax (I was prescribed it -not illegally), but it has been a couple months since I last took it. Not sure if that would make a difference.

Hmmmm. Now that I think about it, I was smoking one of those e-Ciggarettes (I am probably spelling that wrong) last month, but I'm not sure if that would still be in my system after such a long time.
