A stool test indicated that I have H. pylori infection, I ve been taking omeprazole, amoxicillin and clarithromycin as prescribed for 10 days. However, I ve been experiencing worse GERD-related problems such as pain in my upper stomach/esophagus, tightness in my chest, and difficulty in breathing. I suffer from asthma so it feels very similar to it but with the difference that my asthma medications will not do anything to alleviate this discomfort. Should I be worried? Could it be an ulcer? and if so will it heal with time?
