I have been having to burp alot last two days. I felt like heartburn last nite, felt like some discomfort in chest area. My blood pressure is 157/68. Was lower earlier. I m concerned, as I am diabetic, haven t slept well last few weeks, as husband has health issue that is stressing me . I am taking a low dosage of blood pressure meds.10mg, lisinopril. I m having some sensation, not pain in upper chest above breasts.
