Sharing a review of a visit to the hospital for treatment of a sore throat

I'd like to share my experience treating a sore throat last winter. There are many different cold symptoms, including the flu, but I also had a very difficult time dealing with a sore throat last year. I hope this will be helpful to those of you looking for a sore throat treatment.
At first, I thought it was just a cold, with a runny nose and cough, so I took cold medicine. However, it got worse, so I thought it might be whooping cough, so I got tested for it, but it wasn't. I was told that I could still get the flu after getting a flu shot, so I also got tested for it, but it wasn't. The hospital diagnosed it as bronchitis and prescribed medication to help treat a sore throat. I visited several hospitals. I visited an ENT, family medicine, and an internal medicine doctor in my neighborhood, but nothing helped, so I went to an internal medicine doctor a little further away. Fortunately, the medication they prescribed worked, and I'm gradually getting better. Although it was just a sore throat, I initially thought it was pneumonia, so I made an appointment at a larger hospital and had a cardiac ultrasound and pulmonary function test. As expected, the results were normal. Fortunately, thanks to the prescription medication, I've been getting better. However, perhaps because my immune system is weakened, my symptoms seem to worsen with even the slightest fatigue or tiredness. I'm working hard to maintain my immune system. I've also been drinking warm water frequently to keep my throat feeling better. I even bought an electric kettle to give it to me. I've also purchased and am drinking doraji pear juice, as I've heard that doraji is good for the respiratory tract. The symptoms of a sore throat are similar to those of a cold, and even to the flu that's been going around lately. Maintaining good physical condition is crucial for treating a sore throat. It's also crucial to respond quickly to the initial symptoms.
