Did the tremors start before or after your went back to the gym? If after, it sounds to me like the strain from the heavy lifting could have something to do with it... just a guess.

As far as lessened lifespan, I have been researching the heck out of head injuries since my fall, which as now four weeks ago, and I have not found one mention of a shortened life expectancy due to PCS. People with PCS may be at a higher risk for tragic results if they get hit in the head again, but I haven't seen any evidence that having PCS makes us more likely to die young.

I am a very experienced lifter and know how my body works. This is not due to lifting weights.

I fear it may be Parkinson's set on by many blows to the head that night.

Sorry... wasn't trying to imply that you didn't know how your body works. I was simply offering up a suggestion. Hopefully it's not Parkinson's. Best of luck to you.

Just because you don't think you have a neck injury does not mean your body is not responding to a neck injury that has no noticeable symptoms. Inflammation in the neck can cause nerve dysfunction. I have had carpal tunnel syndrome for over 20 years. It gets worse when I have strained my neck, upper back, shoulder and / or elbow. There are many ways to trigger nerve dysfunction.

I get hand tremors from time to time. They increase with stress. I can have hands as steady as a neurosurgeon then not be able to hold steady for every day functions. Just trying to remember the times when my hands commonly tremble caused my right hand to have fine tremors.

I can usually relax out of the tremors.

My best to you.
