Hey everyone

Been a very long time since I have posted as I have mostly worked through most of my issues.

I've had some surgery for other things and I have recently got back into swimming. I used to be a good swimmer (competed) when I was younger.

However, 3 days ago, I went for a swim and dove into the pool. Not from any great height just the edge of the pool. I've always known how to dive as I used to race so I didn't think it would be an issue.

However, the last 3 days I have had headaches, fatigue and lightheadedness.

I am not sure if it is a concussion as I have 2 other things that could be attirbuting to this.

1. I had a PE (Blood clot in lungs) 5 months ago and that can have lingering effects

2. I went out with friends Friday and Saturday and was up until 3am both days (I usually sleep around 11pm) and am not as young as I used to be. I didn't drink but each morning I felt like crap.

So I am unsure what is causing this. Could diving into water theoretically give a concussion or not from that kind of height?
