Tonsillitis and bad headaches from alcohol

I keep getting tonsillitis after drinking. Not like the morning after but night of after as little as a drink or two at dinner. Sometimes it comes after just a couple sips, other times I’m fine for a few drinks. Usually it doesn’t happen it all.

It’s always the right side tonsil/neck region and I can feel the pain radiate up the back of my neck and my frontal lobe. The pain is pretty severe.

Wtf is this?
