I am a 36 yr old male. After a few concussions two years ago, I have similar symptoms. I hit the back of my head skiing, and had pcs symtoms for a few months. They subsided, but i've been left with an inability to exert myself physically.

I can physical do workouts, however, that night, i get extremely disturbed sleep. The next day I wake up with intense brain fog, fatigue, nausea, headaches, my eyes becoming sunken, and I look very sick.

Those symptoms can take a few days to clear up. I absolutely cannot lift weights. Even a few sets of push ups will make me symptomatic. I also cannot perform any sustained activity. 5-10 minutes of jogging is ok, but that is it.

I went to the buffalo clinic with dr Leddy, and he does not believe my symptoms are pcs anymore. I went to a cardiologist, and everything looks good. I do have a history of migraines. In any case, I used to work out 5-6 days a week, now I can barely weed my backyard for more than 20 minutes. I've learned to accept my condition, but I still miss all the physical activity.

Overall, I have made zero improvement in my ability to exert myself in two years. This is leading me to believe that it is a permanent condition, and no doctors can seem to explain it.
