Gerd or some other problem? Problem?

Since last 2 weeks when I wake up in the morning my chest feels heavy and it feels that something is stuck between my breasts. This happens whenever I lie down for a longer time. I keep on getting too many burps through out the day. After I eat sometimes there's a burning sensation for a few mins around the between of my chest. This also happens sometimes when I do some activities. I took c- furo for 5 days and am taking cyra for 10 days now still not much effect. I can breathe properly but sometimes while sleeping one nose gets blocked and while inhaling I feel a wheezing sound. The nose opens up in the morning though. Is this gerd or some lung problem?? Also I took too much of steam inhalation through mouth for 10-12 days consecutively because of corona fear before these things started showing up.
