<s>[INST] So I just had a baby and at the beggining of my pregnancy started having this tingling sensation in my right rib cage at the end of my pregnancy it turned into something very painful where it felt as if someone had punched me there and I was extremely sore now post pregnancy almost three weeks I sometimes get this sharp pain where it hurts to breathe what could this be ? [/INST] Hi and thanks for the query, It could be interesting if you could do a chest X-ray. This could be very important in actually making a clinical appreciation of this condition. Infections, inflammation, asthma are possible causes of this pain. The evolution of these symptoms, pain, tightness of the chest, aggravating and alleviating symptoms could be very important consideration. A physical exam by your physician to ascertain any tenderness on the ribs or junction between the ribs and sternum could suggest Costco Chat Doctor. I suggest you see your pulmonologist for a proper evaluation and management. Thanks and best regards, Luchuo, MD. </s>
