Hopefully they started you on a PPI, sometimes takes several days to work. Don’t force food, do intake liquids - even if ice pops / ice chips - no caffeine, carbonation, alcohol. Smoking increases stomach acids, if you do smoke / vape taper. When ready - bland, alkaline, soft small qty foods. Have they tried a bland, soft diet for you? Are you sleeping on an incline or raised bed ? Lying flat can increase the amount of acid rising in your esophagus. Follow up with your doctor / nurse line if not better and or can not hold liquids.
