My mother had low grade fever for 2 days and then weakness for around 3-4 days, almost 28 days ago. Under doctor's supervision, she had all the medications including that of acidity and other Vitamin tabs, and the prescribed medications got over last week. Now for the past 3-4 days, my mom is facing some stomach upset problems, like in the morning she used to have some loose motion(very mild) for 1-2 times a day and then felt gas problems and weakness also. We have given her Flagyl 400 as of now for the past 2 days but she is having gas problems and weakness also. Please suggest what to do next. Any further medications to add !! Main problem- Gas, stomach upset, weakness (mostly during morning)
