Hi everybody, it's been a while since I've been on here. I just wanted to ask a quick question to calm down my anxiety level.

So I had swim class today and was in the water with my friend sitting next to me on the edge of the pool. Suddenly another person pulled my friend into the water which made him bump kind of hard with his chest/ side into my head. I don't remember if it was really hard or not just that I immediately thought "oh no another concussion". I don't think I had an immediate dazed sensation or anything like that but I'm still not sure whether it's possible to get a concussion from that. Symptoms right now are headache kind of foggy feeling and a little bit of dizziness.

I'm really stressing that whole incident, maybe someone can tell me if that hit could have been strong enough?

Btw I'm trying to get help with my anxiety but sometimes I can't help but stress over stuff like that.
