My husband is extremely tired... What tests should he get?

I just got a double nosebleed..ㅜㅜ

I'm really tired these days because I have a lot to worry about and I'm a bit busy...

What kind of tests should I get at which hospital?

I feel sadㅡㅜ

It would be better if you could tell me about Osan, Dongtan, and Suwon.
