ProAgonist,

Welcome to NeuroTalk.

No, you did not get a concussion from chewing the popcorn kernels. Your dentist will tell you to not chew the 'old maids,' as the unpopped kernels are often called.

You sound very anxious. That is not good for your recovery. It sounds like you read a bit about Second Impact Syndrome online. Although Second Impact Syndrome can be dangerous, it is highly unlikely you are at risk for it. It does not sound like your first concussion was severe enough to put you at risk of Second Impact Syndrome.

Stay away from video games. They are too stressful on a concussed brain. On a 1-10 scale, how bad are your head aches ? Do you take anything to relieve the pain ? Is your neck stiff or tender at all ?
