I'm feeling a bit uneasy because I've had this discomfort and pain in the upper right side of my chest for the past three days. I visited a gastric specialist and he mentioned it might be due to acidity, so he prescribed Pantocid 40mg and Rifagut. I've been taking them for two days now, but the discomfort hasnt improved. Do you think I should get an X-ray to check what's going on? Any advice would be really helpful.
