Hi, I have arthritis and depression, I take naproxen and sertraline. the last week and a half I have suffered with the most excruciating pain in the middle of my chest, especially after eating, the last couple of days I have vomited and I find it easier to rid myself of the pain if I make myself vomit, I am also overweight, I only eat maybe twice a day, I also suffer with diverticular disease. any help will be appreciated, thanks
