When you have a concussion and you overdo it it makes your head more sensitive. When your head is more sensitive it's easier to overdo it. After 1.5 years I was almost fully recovered from a concussion when a small bump to the head snowballed downhill and got so bad that I had to eat, sleep, and poop in the same position for 9 months with my eyes closed staring at crazy hallucinations.

Doctors were so ignorant that they either didn't know what a concussion was, didn't know how to treat one, or prescribed medications that did more harm than good. The doctors’ treatment approach is the reason why my head got as bad as it did.
