After a head to head hit in a recent football game, I got a slight stiffness/crick in my neck that soon went away. No other symptoms. Head concussion?

YouGotACrickcussion. If you have no symptoms now you're sitting pretty!And just a little neck stiffness does not qualify as a true concussion. More like a neck strain.With a concussion, the brain gets a good bounce inside the skull & you'd be left with a headache & other symptoms.You may or may not have blacked out,but the symptoms last a while, sometimes a long while. The spinal cord can experience something similar.
