I recommend Network Chiropractic. They do not (usually) do any structural manipulation, which can be very dangerous for folks with head and neck injuries, as the motion of "cracking your neck" can dislodge clots that can be stuck in vessels of the neck. Networking "gets the nervous system talking to itself again", and that can help with a lot of symptoms.

One thing to keep in mind with concussion, is that it can greatly reduce our ability to judge risks and danger, so you can end up endangering yourself again -- like going up a ladder in bad weather. Even if you don't fall directly on your head, the jolt to your neck and/or the sudden deceleration can cause your brain to smack against the inside of your skull. It's good that you didn't fall directly on your head, but like with auto accidents, you can still sustain damage from the brain colliding against the inside of the skull.

Partying and pushing the envelope in terms of social things may seem like a good idea at the time, but just keep in mind the risk assessment issues - you may be getting yourself in trouble without even realizing it.

Caution is called for, even if everything seems "fine".
