Is it possible to extract Wang Geon on the same day?

I have an important event coming up, but since yesterday, huge, hard pimples have popped up around my mouth and cheeks that hurt to the touch, and it's driving me crazy. I'm worried that if I just leave them alone, they will definitely leave scars, so I plan to get an anti-inflammatory injection and have them extracted right after work.

I originally tried to squeeze it out at home, but I ended up with a pitted scar after messing with it incorrectly in the past, so this time I plan to get proper help from a hospital. I was wondering if there are any available slots for same-day appointments so I can get the injection right away in the evening.

Also, instead of a long-term treatment like a full facial scaling, is it possible to get targeted extraction and injections only for areas that look like they are about to burst with inflammation right now? If so, please let me know if the cost is charged per area or if it is bundled by area.
