<s>[INST] Please I really need some advice! I had a perforated ulcer. 3 years three years ago . Last Feb. I started having severe pain about an inchbelow my left lung almost in the middle. It comes and goes my dr doesn t know what it could be because I have no fever and the flare up is over by the time I get in to see him.I have vomited. With it a few times. But not always. Your opinions. Would help a lot. Thank you for your time Jennifer Eakins [/INST] Hello and Welcome to ‘Ask A Doctor’ service.I have reviewed your query and here is my advice.As you explain the history this is probably the activation of the ulcer again. I hope I have answered your query. Let me know if you have any further questions. Regards, Dr. Jnikolla </s>
