YSK: concussion therapy and rehab exists and is effective. Look up: "concussion therapy + {your city}". Some of them are self-refer

My two-year-old son and husband were hit by a truck as pedestrians. My son has a skull fracture and a bad concussion. He was admitted to the PICU at a Level 1 Trauma Center. He was also seen by numerous neurologists and pediatricians. None of them mentioned concussion therapy. It wasn't until a nurse at a children's hospital mentioned it casually at one of his visits, did I learn that it existed.

I was immediately able to find the clinic, call them, self refer, and start treatment for him. If anyone mentions that they are dealing with someone with a concussion, please mention it.
