Hyperacidity from last two weeks. Done?

Hello Doctor, I am 28 years old. I am home ever since the lockdown. 17th March to be precise.  First my stomach was upset. It started with diarrhoea. After medication from local doctor it got better. I did a course for 15 days of one tablet empty stomach in the morning (medicine name: cap neksium 40) and mucain gel after breakfast, lunch n dinners... During the medication acidity came in control After 12 days I had stopped taking the mucain gel but continued the capsule. (Prescribed by doc) But I am still having acidity and gas problem. I feel like something is stuck in throat. I felt chills. I had checked the temperature. There was no fever though. I have been coughing intermittently. Not much though. Were the chills because of acidity ? My eyes are also slightly yellow above the iris. Because this acidity is there for quite a few days, I am beginning to worry a little bit. Can you pls suggest what can be done ?
