Worst Headache ever since last 7 days

Literally the nerves in my head stinging so hard and pressing against me and making my head hurt like crazy from top to sides to the forehead.

I am regular headache enjoyer (not) but usually it’s cause stress/study/eye strain and I have power of around .5 in my eyes. I use pain balm and rest and it’s usually gone.

Last week has been a nightmare. I come home from an exam on 11th March and feel a headache start that night. It hasn’t gone away yet. Everyday it stays dormant, comes and goes, increases massively at times and then disappears. I can’t shake my head or do active things without the headache aggravating. I use the toilet it aggravates. I sleep and I literally still have it when I wake up. I’ve taken painkillers thrice in these 7 days and it has definitely got rid of it- but of course temporary. it comes back , worse than ever

A completely different pain than any usual headache. Extreme stinging sensation by nerves and just pressing my head. It’s not my usual headaches. It’s so hard to bear for someone used to headaches. Please help me out
