Thank for asking to HCM
I really appreciate your concern looking to the history given here this is case of intestinal infection with Gastroesophagus reflux disease, if I would be your doctor then I would treat you with the following medicine,
1) Tab Omeprazole
40 mg once in day for three week
2) Tab Domeperidone 30 mg once in day for tree week
3) Tab Doxycycline 100 mg once in day for 10 days
hope this information helps you, have a nice day.
