Hi thanks for contacting HCM... You had history of abortion before four month. .. So mostly it has no impact on your stomach pain and infection.... you might have gastritis like infection .... USG you had done that helpful in rule out PID like infection if present after abortion procedure ... Here rule out h.pylori infection by urea breath test .... If it is negative than only omeprazole given .... Cooked oatmeal helpful in soothing stomach .... Excess tea, coffe, spicy foods avoided .... Avoid smoking .... Drink more water .... Avoid stress .... If still pain increasing consult physician for full examination and according to it further work up done ... Take care ....
