I have just had a frightening experience with my pupils.
While getting out of bed in the middle of the night to goto the bathroom, prior to me falling asleep, I put my hands on the side of my face while pressing and pulled them back towards the back of my head, I guess as a way of stretching my scalp/skin. When my hands met the back of my head, I felt pain from the pressure on both sides and quickly stopped, never paid it much thought, and went to the bathroom.
While I was washing my hands I looked in the mirror and noticed that my pupils were extremely dilated, more dilated than I have ever seen them in my life. However, within a couple minutes or so, they were back to normal. Both the bathroom and the hallway outside the bathroom were well lit.
Curious to see if the pain in my head was related to my pupils, I placed my hands on the back of my head and attempted the same movement which previously caused pain on the back sides. I applied just a slight amount of pressure, enough to feel the pain lightly once more. A couple minutes later I looked in the mirror and once again my pupils were extremely dilated. The experience set me into a state of near-panic until they returned to their normal size.
I tend to worry about symptoms too much, and I found this experience to be very scary. I do not want to try applying pressure on my head again to see if it really is linked to the dilation of my pupils. I am unsure if the two experiences are related or just coincidental. Does anyone have any idea what this may be? I had a CT scan a couple months ago following a mild concussion which came out as normal.
