I have had similar troubles on the water too. I had the sensation of bobbing up and down on the waves for almost a week after a couple hours on rough water this summer. It was as if my fight/flight response was getting triggered with every wave.

I forgot to add earlier that I have done the graded levels of exercise before, and built up some endurance. There just seems to be this plateau with lifting and the head pressure. I hope I can regain that progress I made after pushing it too hard last week though.

I had somewhat of a breakthrough after working yesterday. I was at a computer screen all day yesterday, working pretty well. In the afternoon I had to do some work on paper, and could hardly focus my eyes to work while looking down. It was extremely hard to get it done. I then thought that I would go for a run just to test the waters. I ran a few miles on grass as my shins have been hurting with no change in symptoms. I pushed it hard at the gym last week, and noticed that I could row, bike, etc. pretty hard. As soon as I did any lifting my eyes went crazy, but after I relaxed my neck and took a break they were fine again. I think the sharp decline I had earlier this month was not from the cognitive strain of getting back to work after a break, but trying to lift more and not going to the NUCCA chiropractor long enough to have any long term healing.

This article kind of sums up what Mark has said so many times, but I never realized until now:
7. Concussion and whiplash — The Invisible Injury

I never thought about how much the neck can affect the ears and eyes, and other peripheral systems. It looks like I will be holding off on lifting, keeping up with the NUCCA chiropractor, trying to get better posture while working at a desk, and looking for a good PT.

I had to put a total of nine other characters to do this..👍🏃

I heard TBI is actually causing weakness. Do here folks also have problems with testosterone deficiency? It helps to keep mind working as strong body and libido.

TBI definitely causes you to have a lack of energy. After the TBI symptoms end your energy levels will go back up if you're eating right and exercising. I don't think it has anything to do with testosterone.

i am in the same boat. It's been three years since i've been able to exercise without feeling ill. Weight lifting is the biggest culprit. It only takes a few sets of pushups before i get sick. Typically, if i work out, i'll feel fine afterwards, however, my sleep will be heavily interrupted that night. I wake up with severe brain fog, nausea, migraines, and extreme fatigue. The symptoms can last several days. I believe it's linked to the brain no longer being able to regulate inter cranial pressure. Some people have said naproxen or other nasaids could help, but the symptoms are so severe, that I rather not even try.

I've talked to many specialist including Dr. Leddy in Buffalo. No one could give me an answer to this. In fact, most doctors will pretend I never asked the question when it comes up, as they have no way of explaining it.

I used to exercise 5-6 days a week, but life has changed. It took me a year to come to terms with it, and for the most part, I am ok with it. Though, if I could ever work out again, I would be ecstatic.

How heavy are you lifting? I would start with a much lighter weight and if you're OK with it go from there.
