clandestine,

Welcome to NeuroTalk.

As you know, there is no way to predict how long your head aches will last. I have had head aches be chronic for 6 months after a head impact. Your class work is not beneficial to healing. The chiro may help with your neck pain but may be causing enough upper neck trauma to keep you head aches going. If he is doing the 'twist the head and pop the neck' adjustment, it may be too aggressive. Have you done any icing of your upper neck ? Are you tender to the touch behind your ears (the bony part) ?

btw, Add some B-12 to your regimen. 1000 to 2500 mcgs per day. A B Complex likely has only 50 mcgs of B-12.

You might talk with your disabilities department and ask if they have any suggestions for dealing with PCS with a full course load.
