<s>[INST] I slipped on hydrolic fluid hit on my back more on the left side. I heard popping in my chest it took my breath away. That was 10 days ago. It hurts to take full air into lungs. I has ex-rays no broke or fractured ribs. When I cough it feels like a knife right under shoulder blade and also two inches under my left nipple. It is very sharp pain. I almost passout when I cough and there is popping inside my chest from front all around to the back. All pain is in rib 4 and 5 area in the front. and again under shoulder blade close to spine. [/INST] Hi, I value your concern regarding the symptoms. I have gone through your symptoms, and in my opinion get screened with X-ray chest for rib fractures a second time and if required appropriate by your doctor get an MRI done to see some occult injury that would have been missed on the X-ray. Hope this answers your question. If you have additional questions or follow-up questions then please do not hesitate in writing to us. I will be happy to answer your questions. Wishing you good health. Special note-Any medication prescribed needs to be taken after consultation with your personal doctor only. </s>
