I had a cold on Thursday, so I went to the hospital. The doctor asked my condition. I said “I have a cough violently and my voice is strange.”. Then the doctor said “Do not eat chocolate, and do not drink coffee, alcoholic drink and something cold. And I’ll give you medicine. You can eat this for 3 days. If you eat this medicine, but you can’t stop a cough, you should come here on next Monday. You need to test vocal nodule.”. I was afraid vocal nodule test. Tomorrow is Monday!! But fortunately, I get well of a cold.
