I suddenly vomited, so I visited the internal medicine department.

I kept vomiting because I couldn't eat well, and maybe because I vomited severely, I vomited blood.

I went to internal medicine because I was feeling strange and worried about something.

It seems like you are running a private clinic. From the name, it looks like an old building, so they are providing medical services there.

The elderly doctor is seeing patients. I'm not sure if I came late, but there is no one else outside of me.

They gave me an injection and prescribed medication. I will be taking the medicine for a few days. It's been a while since I had an injection in my arm.

They say you'll get better if you take the medicine properly. Since you're taking the medicine well, you're doing okay.
