Hello my name is Kenny and I am 39 years. My story started around February to March of last year 2016. I started spitting out speck of blood. I immediately quit cigarettes because I was so worried. I then received a chest x Ray and it was normal except doctor said I have mild apical pleural thickening in lung. He said don't worry. 2 months later I started developing chest pain. It's not sharp pain but more like ache pain or sore pain. My doctor diagnosed me with costochrondritis. He said it should go alway on its own. Then I got a chest ct Scan now in the 4 months period. Normal also except mild apical pleural thickening. Fast forward while still having all the same symptoms but the spitting up blood seem to stop. I have another chest x Ray in December of 2016 because I was coughing up thick green mucus. My doctor said I am normal. In mid Jan. Of 2017 I stared getting intermittent right shoulder pain. More like aching pain. Problems I still have now: 1) I still have chest pain now for about a year and 1 month now. 2) I still cough up thick brownish mucus even after over one year of quitting cigarettes. 3) I still have right shoulder pain for about three months now. Does any have any information on costochrondritis and how long it should last? I just don't feel like it should take this long and not heal yet. Maybe I have other issues. Does anyone ever quit cigarettes and still cough up brownish mucus for over a years? Sometime when I am talking it comes up and I need to cough it up. Also any info. On shoulder pain. Thank you for any info. My doctor pretty much ignore my concerns now at this point.
