I am 24 years old. Recently, I got an endoscopy. The report shows that I have erosive gastropathy. I have been using medicines for one month. Now, for a few days, while spitting phlegm a small amount of light red blood comes out from my mouth. I also have some throat and chest pain. But, I do not have a cough. I have joined the night shift job and had sudden weight loss. Please give your suggestion.
