Yes, most of us have experienced these problems. You should expect that every time you push your brain's limits that you will need a week or two to recover. You can not be in these environments if you want to recover in the near future. You will be making obe step forward then a step backward.

It just does not work to challenge your brain like you did.

The physio is not for your brain. Your brain needs quiet rest.

I forget how much B's you are getting but you also need good amounts of D3, etc . The whole regimen is needed to help the brain tolerate stress much less recover from your concussion.

Hopefully, feeling scared will cause you to be more cautious before you go out again. I have had to cancel my dinner order and walk out of restaurants.

Do you take ear plugs with you ? You should always have them in your pocket.

Your MRI will not tell you anything helpful. Your brain is injured at a microscopic level. The doctor can not help you get better. You are in charge. You need to be consistently easier on your brain. No pushing it, even infrequently.

Many here have tried push through and after a year of frustration, finally gave in and slowed down and saw improvement.

My best to you.
