<s>[INST] I took a fall jumping my bicycle and landed awkwardly on my left side back.  There is pain in the left mid side of my back only if I twist wrong or cough, sneeze, blow my nose etc but normal breathing is ok. Im thinking fractured rib but I never heard of anyone fracturing a rib in the back area. Should I be worried? [/INST] Hello, Rib contusion is not always visible on x-ray. You may need to do MRI or HRCT to see details of injury. I will advise consulting to orthopedic surgeon. Medication like muscle relaxant and analgesic will reduce pain along with it use rib support belt. You may consult physiotherapist for pain management, he may start TENS, or ultrasound which is helpful in your case. Hope I have answered your query. Let me know if I can assist you further. </s>
