I have been thinking back on my life trying to remember what all I've done to my brain. Since this is my first diagnosed concussion, it seems odd to have such lingering symptoms. I am certain I have concussed my head many times in the past, but never got diagnosed b/c I never sought treatment. Just took a lot of aspirin and shook it off.

Now I'm also thinking about very loud noise, and wondering if it's enough to be considered sub concussive shock. For example, shooting skeet w/o ear plugs. I used to shoot a lot of skeet and never used ear plugs. Before that, when I was a teenager I would go to a lot of loud heavy metal concerts. I remember one in particular, the Scorpions, made my ears ring for two days after. Would anything that loud cause concussive stress on the brain?
