I visited the hospital because of a severe cold, and Dr. Lee Yong-ju used a device to check the condition of my nostrils and throat. He also asked if I had clear nasal discharge and how severe my sore throat was. So, after answering my symptoms, the strength of the prescribed medication was adjusted, and after taking the 4-day dose, my high fever went down to some extent and my headache got much better. To go into detail, I was in great pain for two days before my visit because I didn't get better even with over-the-counter medication, and my headaches were making it difficult to even do my daily life. However, after taking the medication, I felt a little better the next day, and after the fourth day, my headache symptoms completely disappeared. Also, the waiting room had a bright atmosphere unlike any other hospital, so I was able to have a cup of warm tea after the treatment and return home calmly.
