I just got an IV at Suwon City May Hope Clinic.

The nurse who helped me with the IV drip was a bit loud, but everything was fine.
The IV fluids at May Hope Clinic are great. My body was so sluggish and fatigued that I felt like I couldn't endure it anymore, so I went. The reception was calm and not overly formal, and the wait time was shorter than I expected, which was nice. The director asked me about my condition and any recent overexertion, and explained the type of IV fluids that would be best for me, which gave me a sense of trust. I never felt like I was just being told to hurry up and get the injection.
While I was getting the IV, the nurse (who spoke a bit loudly) was able to find the right vein and insert it in one go. I didn't feel any pain or bruising. She checked me from time to time to make sure I wasn't feeling any discomfort, so I was able to lie down comfortably. The facility was clean and quiet, so I didn't feel like I was getting more tired just from coming to the hospital.
I think it would be really good if the patient could just lower their voice a little while they rest and receive treatment.
