That does not sound normal, you need to get this checked out. Meanwhile do work that doesn’t require too much thinking until you can get it checked.

I suspect that, under such conditions, the headaches are normal for someone at my age.

I can go from 0-100mph on a dime, which may have led to the headaches. I'm not passionate about coding, so I dive in without being warmed up.

Contrarily, with passion and a slow pre-heat, the headaches probably wouldn't happen. But I am not a passionate coder.

I may need to strongly consider nurturing non-coding tech skills. I'm doing some (very part time) engineering research for food money. No headaches.

Coding may be out for me, that's all. I can still participate in tech otherwise.

It depends. If you haven't coded for a while, been homeless (= probably sleep deprived) and then do (making this up) a couple of 10 hour sprints on coding, especially with no rest it will hurt most people.
