Please help. i've had a headache for the past 4 days (non-stop) and the only thing that makes it better is closing my eyes. i feel pressure in my eyes whenever i look at a screen too long, and my eyes are fatigued and in pain?

You should see an eye doctor for examination and treatment. Your symptoms could be due to eye strain so avoiding electronics as much as possible is prudent until you get seen. Your symptoms could also be due to dry eyes so warm compresses 15 minutes twice daily as well as artificial tears may be helpful. If you are having vision changes, go to urgent care or an emergency room! Best of luck to you!

Alternative thought: Your eyes are likely fine, but the visual issues perhaps due to photophobia secondary to a migraine headache. Surely, see eye doctor, but maybe next step is neurologist.
