You have already experienced long term consequences. Being unable to drive for a month means you suffered a serious concussion. You should be requesting a full Neuro Psychological Assessment to see what functional limitations you have that are likely due to head trauma.

To correct DavOD, There is no way to predict long term outcomes.

Personally, I would not continue in such an occupation. Years ago, we had a 2 persons here on NT who had been repeatedly been beat by inmates in prisons and jails. Both ended up with serious long term disabilities.

They felt limited in their choices due to a need for employment.

Unemployed and disabled is much worse.
