Want a quick guide. The new medications.

I have been experiencing nausea and diarrhoea since last Thursday. I consulted a doctor on Saturday, and he prescribed Esomeprazole for 7 days along with probiotics for 3 days (three times daily). By Tuesday, I felt somewhat better, but not completely recovered. So, I visited another doctor. He did not review my previous prescription and gave me new medications: Dompan (to be taken before food), Maxicef (after food), and G-Blac. Since I had already completed a course of probiotics, I did not take G-Blac. However, after starting Dompan and Maxicef, I began experiencing stomach pain. The pain does not occur after eating food, but it starts after taking these medicines. From the next day onward, the stomach pain continued. Additionally, I have noticed small bumps appearing around my eyes, and I am unsure whether this is related to the new medications.
