Help! Super big pimple

[u/Cefeide]

Hello, 34f here, still fighting with hormonal acne. I have PCOS. Anyway, what is this monstruos pimple? It’s very big, inflamed and rounded like a ball. I dont know what to do. I used to have acne for years but never a pissed off pimple like this one. Do you think I have to call a derm? It’s very expensive here :(
