Two weeks ago, I was in a car in the seat behind the driver. Just when the driver was about to take a turn, I decided to shift my position from the seat behind him to the other one to have more leg space. Just as I was standing up, he was taking the turn, and he didn't see that in the middle of the road there was a trash can. So when he finally saw it, he suddenly slammed the breaks, and I fell and hit my head on the soft head prop of the chair in front (hit the top of my head basically, the part you would see if you were looking at me from above). I don't think it was a big hit since I remember my glasses stayed on as I fell. I didn't lose consciousness or blackout. It didn't hurt much since the thing was soft, but I was somewhat shaken/shocked. Of course the driver apologised, and we continued the journey. I don't know if it was just because I became paranoid/anxious about it immediately, but I think that I did feel a sort of pressure around the area for awhile after. The hit left no bruise, like if I touched the area of my head where I got hit, I wouldn't feel any soreness, pain or bump any of the following days.
For a week I had no symptoms, apart from just being anxious from time to time about it. Then one day I felt a kind of pressure sensation behind my eyes, or in the middle of my eyes. It's been another week now, and the sensation came and went several times.I don't know if it's because I've been using the computer more... It's never been strong, but I did notice it. It didn't stop me from continuing to do whatever activities I was doing (as in it was just there, it wasn't anywhere near being painful enough to be debilitating). I'm wondering if this is just from my anxiety about the hit especially considering that I didn't blackout, didn't lose consciousness, and was perfectly fine immediately after the hit. The speed of the car couldn't have been very great since he was just taking a turn. The pain is also in a completely different region from where I hit my head. Could this be from the hit? It worries me a lot, but most of the time when I can be entirely rational about it, I do think it is just my anxiety. Please let me know on more expert opinions!
