I’m a 21 year old male with post concussion syndrome, possible cte and anxiety from a lifetime of contact sports and being a reckless crazy child.

Just now I was in the shower. I use a special shampoo that comes in this thick hard plastic bottle with a rock hard plastic ‘water bottle’ type mouth to it.

There was not very much shampoo left so I took the normal cap off and started shaking the bottles contents directly on to the top of my head under the water. It still had some product left in it so it was quite heavy. I slipped up as I was shaking the bottle quite rigorously and ended up hitting myself on the top side of my head with the hard bottle mouth. It didn’t hurt that much just stung a tiny bit but it definitely felt like a devastating blow. Left a bit of a sore area I believe.

Do you think this would cause further brain damage or is it more likely to be a sub concussive impact? Thank you very much.
