ConcussedGuy,

At my very worst point I experienced hypersensitivity.

This entailed post concussive headaches, extreme light sensitivity, and the ability to hear conversations clearly in the downstairs of the house (like they were in the same room), painful tinitus and hypercusis, as well as chronic fatigue and sensory overload. I would also get the crushing sensation if I over exerted myself.

I believe this was down to either swelling, changes in cerebral blood flow, dilated blood vessels, neuralgia - or all of these.

Whatever the crushing was it has left me with Neuralgia and numbness in my teeth and gums, and a degree of light sensitivity. Thankfully Cymbalta has helped my Neuropathic pain and hopefully Lyrica will help it further. For PCS headache Imigran (Sumatripan) really helped.

Some anticonvulsants can indeed help neuralgia - Lyrica is one of these.

The fact is the medical world do not understand Concussion or PCS fully. I hope you recover!
