Headache when reading/concentrating

Hi guys!

When I have to read a text or to concentrate or sometimes just talk, I get this massive head pressure in my head. This makes me feel so tired that I can’t continue to read/work. The more complex the text the earlier it happens, usually after 15 min. This is horrible. I can’t work anymore.
Do you experience the same? Any ideas what might help?

I had it in the first few months, today I’m better. I got better naturally

I had this as well, I noticed it was much worse with caffeine intake. Mine was never that bad but got better naturally as well over time.

I have the exact same thing man. It’s so bad I can’t really work past 3 pm anymore. What helps for me is going for walks in between computer time.
