When I was walking my dog the other day, I took a step abruptly off a curb and felt a really unpleasant lurching in my head. My knee may have veen locked at an awkward angle. I felt really weird. I tried to tell myself it was nothing, but I have been feeling truly miserable since then. I feel like I've gone 100% backwards and I'm really really scared that I've reinjured myself

I attributed it to pillow in another thread, but now I've realized this.

Could you get a concussion this way? I recall reading marks post about something similar and im honestly kind of panicking

I apologize for multiple posts in a short time but I'm really scared. I feel like I'm losing it
