I am a 45 yr woman with diabets and hypertension and have acid reflux and a herina in my espoghgus (sorry about spelling). I have been out of medicines for several days for acid reflux and this acid is making so sick, my stomach feels like someone has used it for a punching bag, and I have been nausea and this morning I was coughing up blood what could this be. I also had kidney stones removed last year, and I am having pain in my back as well.
Frank bright Blood in cough can be seen in patients with bronchitis or tuberculosis and coffee co loured blood is seen in patients with gastritis due to bleeding ulcer in stomach or lower part of esophagus. As per your history it seems it is due to some bleeding ulcer. You must show to a gastroenterologist and in the meantime start taking your antacids like Cap pantoprazole along with antireflux medicines like mosapride and tranexamic acid.
