I got my first concussion on 27th October 2014, which was roughly 9.5 months ago, and have developed PCS shortly after. I have a few questions about my current situation.

1. I'm dealing a lot better with anxiety of hitting head right now, after going to CBT for about 12 meetings, but I still have a few concerns. For example, if I sit on a chair or on my bed, I'm afraid to lean back with my head to the wall, because I'm afraid that I'll lean back too quickly, and the impact will be enough to cause another concussion (my first concussion was caused when I ran into a wall and got hit on the right side of my head).

So how can I be confident that I don't lean my head back too fast to cause a concussion?

2. Since the PCS started, I'm having a few physiological problems, such as facial sweating and significantly increased dandruff amount. I wash my head every day with an anti-dandruff shampoo, yet I still have dandruff - it wasn't like this before my PCS started.

I also have more facial sweating, and when water get into my eyes, they start burning and it really hurts. If I'm running, for example, and sweat gets into my eyes, it burns a lot and I cannot keep my eyes open for more than 5 seconds because of the intense pain. I have to wipe the liquid that got into my eye (water/sweat) with a tissue - until then, it keeps hurting.

3. My PCS made me think about something - why was I "fragile" when I get that hit to the head? I got numerous hits to the head in the past - in one of them, someone took a 5-6 kilogram backpack and smashed it into the right side of my head. About 5 minutes later, I started having a metallic taste in my mouth, which indicates a concussion, but even though it was probably a concussion, it didn't develop to PCS. I panicked a little that my eardrum might have been hurt, but that concussion from the backpack didn't develop to PCS and I don't remember feeling any of the typical PCS symptoms days/weeks later.

So why only the concussion on 27 October 2014 caused me to develop PCS, and all the hits to my head prior to it didn't cause me PCS? It makes me feel "fragile" that suddenly, one hit to the head was enough to spark PCS, whereas the previous ones were not.

I'm making progress, but I'm confused about these things so I would really appreciate any help.

Thanks,
