question: I ve been getting sharp pains in my chest for the last 6 months. They last between 5-10 seconds and happen inconsistently if I take a deep breath after the pain my chest feels tight and sore. I don t get it every day i can go a few days but it happens at least 2 or 3 times a week. I ve read that it could be pleurisy. I m just wondering what would cause this?
