Could it be esophagitis?

It feels like something has been stuck in my throat for the past few days.

I had chest pain once or twice before, and since I had experienced this before, I went to the hospital and was told it was probably esophagitis, so I took the medication and it was okay. But this time, even after taking the medicine, it doesn't get better. Actually, I missed taking the medication quite a few times... I think I need to go back to the hospital again. ㅠ

It must be esophagitis, right? These days, you probably can't even make an appointment for an endoscopy...

I'm worried ㅠ
