Headache when drinking some things

I (25M) have started getting a mild headache whenever I drink something that is not plain water or milk, but only while the liquid is in my mouth.

The headache is in the lower back of my head and it’s just kind of a quick stab while the drink is in my mouth.

I’ve tried a bunch of different drinks, sodas and anything bitter (like lemonade) seem to be the worst, but even water with just a bit of sugar will still cause mild discomfort.

No medical conditions, no medications, no drug use. I do drink alcohol a few times a week, but I have not had any for the past two days.
