hello, i can understand your concern. i wouldnt advise you to start an antibiotic on your own without consulting a physician. since you have already taken one week course of metrogyl with which usually most of the infections would cure. i would suggest you the following medications along with an ultrasound abdomen. kindly take tab pan 40(pantoprazole) half hour before breakafast and dinner, and take tab cyclopam(dicyclomine) to be taken after food twice a day for five days each, tab darolac once daily for five days. eat foods which are easily digestible and are rich in fiber. get an ultrasound abdomen done, this would help us in diagnosing the ailment. kindly follow the instructions and get back to us with the ultrasound findings. feel free to ask further questions. wish you a speedy recovery. thanks for choosing HCM
