wtf is up with that? today is my "1 year anniversary" and im overall in good shape except for like 2 lingering symptoms but the exact spot i hit my head still feels as sore as it did the day after i hit it

if i shake my head side to side i can still feel my brain is extremely sensitive and the whole back left side of my head feels swollen and tender

its been 1 year how has this not healed yet? my neuro says there is no way there is still bruising there but i know my own head and it still feels banged up

am i basically stuck with this feeling for life since its been 1 year? my neuro said im stuck in a migraine state and im hoping once i shake it i wont have this sensitive feeling in my impact spot. it feels exactly how a headache feels when you move your head to fast....that jolting tender crappy feeling
