hello my name is william and i have been stricken with chest pain all year round due to reoccurring Pneumothorax (Collapsed Lung). i suffer with the pain but the pneumothorax doesnt show itself on any xrays and such most of the time. it shows itself every 5-7 months. first time was back on 4/20/09 but the pain first started in December of 08 and i am still suffering. the doctors tell me it will blow over but two years going on three i dont know. i was just wondering if any doctors had some input, had the same issue themselves, or had/has a patient dealing with the same thing. And yes im a skinny teenager. i have seen lots of specialist and no one has answer or some theory for me to go on they ruled out athsma, a bad fall and many other thoeries thats why im here.

Welcome to Chat Doctor Are you a thin, tall person who smokes regularly. There is possibility of multiple cystic formation of your pleura which keep rupturing with stress, loud noise, high pressure areas, coughing as well which is causing recurrent pneumothoraces. But usually pain isn't present with an uncomplicated pneumothorax unless there is infection or inflammation. Have other tests been done to rule out TB, Rheumatoid arthritis, Eosinophilic granuloma etc. which are common causes of recurring pneumothorax associated with pain. How is your chest X-ray, has a CT scan been done of your chest. Are your blood counts normal. You need to avoid going in high pressure areas like swimming deep, loud music concerts, coughing, and stop smoking if you are a smoker as well. Get investigated for the possible causes of recurrent pneumothorax as well to get relief from these problems.
