I am a 31 year old female.  I bent over last night and it felt like my lung got pinched in my ribs.  I had trouble breathing for about 20 mins afterwards.  Tonight I was sitting watching a movie when I doubled over unable to breath and I have had shortness of breath and a sharp stabbing pain in the same area as last night?  Could this be a collapsed lung?
Thanks for your question on Chat Doctor. I can understand your concern. You were having blunt chest injury last night. This kind of injuries mostly cause musculoskeletal pain. But when severe, they can cause lung injury like pulmonary contusion, pneumothorax etc. And they can cause breathlessness. So better to get done chest x-ray to rule out lung injury. If chest x-ray is normal then no need to worry about major lung complications. Simple musculoskeletal pain is the cause for your symptoms. So avoid movements causing pain. Avoid bad postures in sleep. Avoid heavyweight lifting and strenuous exercise. Take ibuprofen tablet. Apply warm water pad on affected areas. Don't worry, you will be alright with all these. Don't worry about collapse lung or other severe complications. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
