<human>: I have had a sharp pain under my left rib cage for 3 days now, and today i am seeing spots, i am dizzy and the pain is getting worse. I am also tired and have had some mild diarhhea (i did eat taco bell last night ) could this be a pulmonary embolism?
<bot>: Hi and thank you for choosing Chat Doctor to post your question. I read carefully your question and understand your concern. Chest pain it can be a serious symptom and needs careful evaluation since it can be related to serious heart and lung disease. If I was your treating doctor I would need to know a bit more about your age, your past medical history since there are risk factors that increase the clinical probability of pulmonary embolism such as:immobilization, surgery and trauma, pregnancy,oral contraceptive, current or past history of thromboflebitis etc. I would order a chest x-ray to exclude lung diseases that present with chest pain and d-dimmer test that is used to help rule out the presence of an inappropriate blood thrombus. I would also suggest an ECG and cardiac enzymes to exclude serious heart problems. I hope my opinion can be a help to you. Wish you good health.
