Hi all,

I'm beyond the end of my tether with this tingling sensation in my head near the site of impact.

What the hell is it?? Does anyone know??

It becomes worse with any kind of physical or cognitive exertion. Then the other symptoms (e.g. slowed thinking, difficulty speaking) begin.

Is it reduced blood flow? Sensitivity to increased blood flow? Reduced glucose uptake?

All MRI's and other tests are normal.

Doctors say there is nothing wrong with me but that I should not undertake strenuous exercise... Isn't that a contradiction?

Thanks as usual - I'm feeling hopeless about this sorry
