I'm Not Feeling Well. I May Need to Go for a Major Check-Up Next Monday.

I've been having stomach pain recently (I don't know if it's stomach pain, I haven't checked, it's just under the left rib)

The pain is really severe and unbearable (the pain makes my forehead sweat)

I will update as usual today and tomorrow. The hospital will be open as usual next Monday.

I want to make an appointment for a gastroscopy and colonoscopy. I may have to be hospitalized. I have to ask for leave in advance.

(It doesn’t have to be Monday. I heard that you have to make an appointment for gastroscopy, but I haven’t been there.)
