At first, I visited the internal medicine department because of a runny nose and stuffy nose. And I took the medicine for three days, but my nose didn't get better. I went to the ENT clinic without thinking much of it, but the doctor said I might have sinusitis. I was originally a healthy woman, and I was healthy enough to live without knowing about rhinitis, sinusitis, or anything else. So I was surprised. I was surprised at how thoroughly the doctor cleaned my nose of mucus and washed it with saline solution. They suggested I get a CT scan and explained it to me, but it seemed a bit serious. First, they told me to take antibiotics for two weeks and to drink lots of water. Thank you for your kind explanation. I want to visit again when I am sick. thank you
