Wondering if anyone could give me any insight or have been through something similar. My mom was fighting off pneumonia for a few weeks and after many failed antibiotics they finally found one that worked (augmentin) now I've heard this can be quite harsh on the system but now she's plagued with nausea, vomiting, diarehea, burning stomach, and lower abdominal pain. She also has pretty bad acid reflux (has for many years) I'm extremely worried about her and fearing the worst. Has anyone had something similar to this after strong antibiotics?!
