I was wondering if short anxiety attacks can make your symptoms get worse for a temporary amount of time. I usually don't have any but I did something that theoretically could cause a concussion but in reality has a 0.0001% of causing one and I just couldn't stop thinking about it. I started obsessing over it and playing the scenario over and over which only made it worse. And while I felt pretty good most of the day one slight change seemed to make me start wondering and brought on worse symptoms. Is this something that anxiety can cause and simple confidence can restore? Thanks for any responses.
