I was walking on the street and some guy bumped into me extremely hard (he was running). I didn't stumble back or hit my head against anything but began experiencing symptoms later that day. Could this be a concussion or anxiety?

It's just anxiety. If it was hard enough to cause a concussion, you would be suffering very severe whiplash and be in the ER complaining about your neck. You also would have been knocked to the ground by the force.

Less than 2 G's of force. No more than stepping off a curb.

Anxiety.

IBR,

My guess is anxiety too.

I was busy texting my wife the other day and trotted into a partially down garage door on my injury site. Jumped in my son I laws truck and headed to my grandsons soccer game. He proceeded to take a short cut through a field in his lifted extremely rough ride truck and jarred my head around more.

I was lucky enough to keep the anxiety down and was no worse than Anyone else would be for both incidents. It was tough staying calm though.

Bud

still having symptoms: i suppose at this point it can't be anxiety but actual brain damage?

Anxiety can cause a cascade of symptoms that can last for days or longer. Anxiety feeds anxiety. The startle response from the bump can set off a whole range of chemical reactions that need to settle down and balance out.

Startle response is like the 'fight or flight' response. It is chemical, not physically traumatic. If you feed the startle response with 'Did this bump cause brain damage?' the effects and anxiety can last a long time. Some take weeks to get over a startle response because they are convinced there was damage caused. Only when they get distracted with other things in their life and forget about the event do they let go of the anxiety and get back to normal.

NO, this was not brain damage.
