brett,

Welcome to NeuroTalk. Sorry to hear of you injury. Your symptoms sound like classic Post Concussion Syndrome.

Your rugby history leads me to believe you have had many more than 3 concussions. Any time you had a head impact with even a bit of change in sensation, it was a concussion. Plus, you have likely suffered many sub-concussive impacts. You sense of being 'bullet proof' adds to the complexity of impacts that can effect your brain. Plus, getting blotto drunk is equivalent to getting a concussion in how it effects your brain.

To give your brain a chance to heal, it needs quiet rest. That means a few weeks off work or minimal cognitive effort at work in a quiet environment. Quiet means limited sounds and visual stimuli. Even smells and tactile sensations are stressors to the recovering brain.

Avoid alcohol, caffeine, MSG, artificial sweeteners, intense sugars, etc. Good meat protein will help with the amino acids your brain needs.

There is a regimen of vitamins and supplements that also help the brain cleanse from the toxins released during an injury. I have posted it a few times recently. Check my other posts for the list. Left click on my screen name then click on 'see other posts'

You are not bullet proof any more. You likely are arriving at a condition called Multiple Impact Syndrome. This is when an accumulation of impacts leave the brain with longer term symptoms. They may take months to improve and some symptoms may not recover to prior levels.

Please keep us informed. There are plenty of good people here.

My best to you.
