<s>[INST] My ten year old has been complaining with not being able to get good breaths, he says it is like trying to breathe through a straw. He says that if he takes a deep breath when this happens it hurts really bad. He has been saying this for over a week what is your opinion? [/INST] Hi thanks for asking question. Here first your child could have severe muscular strain by heavy exercise or any unaccustomed activity ... Rest needed for it. Simple analgesic taken if needed. As your child having history since week. His physical examination done with auscultation for any rhonchi or CREPS. If fever also present x-ray might be needed for rule out any consolidation as in pneumonia or changes regarding bronchitis or other interstitial lung disease. And treated accordingly.... If ribs are tender to touch then it might be Costco Chat Doctor. Take care... </s>
