Chris,

Welcome to NeuroTalk. What you are experiencing is not uncommon.

You do not need to be seen by another doctor. You need quiet rest and good nutrition. No caffeine or alcohol. Minimal visual or auditory stimulation.

The jarring from the 3 mile run likely caused your symptoms to get worse but not a major concussion. Your brain was already struggling and you just exhausted it to the max.

Get plenty of healthy fluids. We have a vitamin and supplement regimen that many of us rely on. If you are up to taking on a serious vitamin regimen, let us know.

Also, it is not uncommon for concussion symptoms to get worse after a few weeks. The brain has brain cells that are struggling. If they continue to struggle, the brain finally shuts them down and lets them die off. The stress of the run could have also be enough to tip those struggling cells to a point of collapse. So, it is impossible to say whether your run caused the problem or if it was an inevitability.

So, try not to worry. Anxiety is bad for concussion recovery.

Let us know how we can help.

My best to you.
