Hi everyone, new person here! Been searching for info on this symptom, but no real luck!

So I had a mild concussion in early May - silly me bent over to pick something up and forgot how close I was to the house - bonked the top left of my head on the brick wall.

Anyway, brushed it off then as the pain went away after a few minutes, but the next day started getting classic concussion symptoms (headaches, light-sensitive, ringing-in-ears), so took myself to hospital. Passed all the cognitive/motor function tests so the doc told me it was just a mild concussion and I just needed to get some rest. Lots of fatigue and insomnia for a few weeks, but eventually everything seemed to improve.

However, one symptom persists. I have a strange, intermittent sensation of muscle or skin tightness on the right side of my face. It's generally near the eye and in the check area, sometimes down to the top lip. It feels a bit similar to what happens if you put an astringent like witch hazel on your skin. There's no paralysis - though at its worst I sometimes notice my right eye doesn't open quite as much as the left (though this is only a very, very subtle difference). This symptom only showed up a few weeks after the concussion, but I'm pretty sure it's related, as I did occasionally experience some brief tingling down the right side of my face in that first week.

I got freaked out enough by this to ask my GP for a referral to get an MRI - but that came up all clear, which certainly calmed me down a lot. After that it did seem to become much less frequent, but recently it's worsened again. Trying to work out what triggers it and I think stress and tiredness definitely seem to be the biggest factors. Experimenting with diet and different levels of exercise has been frustratingly inconclusive.

Soooo, after Googling the hell out of this, I'm assuming it's some kind of facial nerve damage, but not sure if I should just ride it out, or whether I should be seeking out a neurologist (if only for reassurance that it's not serious!)

Anyone else experience this weirdness? Fortunately it doesn't stop me from doing things like many other concussion symptoms can, but it's always a disturbing reminder that something's still not quite right in the old noggin!
