Hi all,

I'm just attempting to narrow down the possible causes behind my symptoms as well as factors that aggravate these following a concussion 12+ months ago.

Symptoms; brain fog, tingling/fuzziness on left side of head (especially upon physical or mental exertion), mixing up words, word finding difficulties, stuttered/slurred speech, blurred vision in left eye and difficulty hearing in left ear.

Factors that aggravate symptoms; any form of mental or physical exertion, even a bowel movement..

After 24-48 hours of no mental and physical exertion my symptoms decrease and I am back to 95% normal.

Symptoms immediately return upon mental or physical exertion.

Quick recovery to 95% may indicate that my condition is non-permanent and does not involve severe 'damage' to brain structures - maybe something is just being obstructed/blocked in the 24-48 hours following mental/physical exertion?

For anyone with experience in this area, are there any structures of the brain or nervous system that could be affected following mental/physical exertion and simply be causing my symptoms? E.g. brain nerves being obstructed by blood vessels, lack of blood flow, inflammation etc.

MRI of brain and neck are fine.

Many thanks!
