Hello, I m 18 and I m a smoker. I ve been smoking for two years and I m not proud of that. Today I ve had some sharp pains in my right rib cage and going to my back, I almost couldn t move and catch my breath. Right now, it s better even after I had a cigarette, but I can t take deep breaths. Also, when I bend forward, I can feel something in my rib cage rolling below the place of the pain, it s almost the same feeling when your heart starts beating really fast. Should this go away or should I see a doctor?
