Head trauma after 15 days

[Bills17]

Hello friends, Help please.

On day 15 after a 1700 FUE i was hit very hard in the back of the head ( donor area) ..So hard that i needed to go to the Emergency room and had a minor concussion,but no extirior bleeding present.Most Doctor's have said at day 10 your ok.Some say day 14,some say a month. I'm worried a Hematoma may have damaged my follicles My surgeon seems to think I'll be ok,but i sure would like to here a few opinions from others.
