I had an egd no issues found but i still have chest pain and soreness also unable to get satisfying deep breath at times can this be effect of cozaar (losartan)?

Drug side effects: Cozaar (losartan) which is of a class of medications referred to as ARBS, are not as clearly identified with your side effects - although some can have a dry unable to clear cough. The close class of meds called Ace-inhibitors can be associated more with this side effect. What you are describing could be associated with multiple causes including heart, lung or a medication effect. Talk to your doc asap.
