Hi an also, I'm about 14 week post concussion/ptvs. I have brain fatigue and headache that

can last up to a day after sex. I feel this is related concentration and creating a visual image

in my brain. Plus the rise in heart rate. My PT has on stationary bike program and once my heart goes over 110-120 I get a heart rate. I hope this make sense. Reading over what I write exhaust me.
