I've been experiencing some chest pain in the center of my chest after I eat. It's been happening for the past couple of days, and the pain comes and goes throughout the day. Sometimes, the pain is in my heart and left chest, and it's really bothering me. I also feel it a lot in the right chest, in the middle of the two chests. I can't easily visit a clinic because it's far away and with corona, I'm trying to stay safe. Is there any medicine you can suggest that I can get from a medical shop nearby? I'm really worried and would appreciate your help.
