A hospital in Suwon that specializes in treating menstrual pain

It wasn't like this before, but for the past few years, I've been having stomachaches every day.

I always take Tylenol.

But I haven't been to an obstetrician/gynecologist since I was born, so I don't know which one would be good.

Wouldn't it be better to go to an obstetrician/gynecologist rather than an internal medicine doctor?

I'm curious about a good place to get treatment in Suwon.
