Thank for asking to HCM
I really appreciate your concern, as you gave the history here but that is not related with the symptom given here your symptom of stomach pain must due to the gastritis
that might be developed because of the medicine that you are taking "Tri-cyclen" certain drugs induces gastritis and to avoid that PPI (Proton pump
inhibitor should be taken along with this drug) and the best PPI is "Omeprazole
40 mg once in day" hope this information helps you, have nice day.
