Find a good neurologist that deals with PCS,many don't. There are many sub specialties in neurology so make sure your neurologist has direct experience with PCS and traumatic brain injuries. After my concussions I found a neurologist and went to him for awhile until I found out that his specialty was altzheimers. I finally found one that specialized in migraines and TBI's and migraines, I hope this helps,good luck
