I haven't been on healthboards in a long time but need some help. Last night I was putting on makeup and when I was looking in the mirror, I noticed that my right pupil was a lot bigger than the left one....I had a headache most of the day, but didn't think anything of it...when my husband got home he did an "experiment". He saw the difference and used a flashlight to check my pupils. The right one didn't react at all, my pupils are back to normal, but I have almost a sinus headache with pain in my face......any ideas???
