<s>[INST] I smooked hookah for the first time ever two days ago and woke up with a pain in my left jaw (near molars) .  It hurts when I chew, yawn or anytime I open my mouth a certain way.  Smoking that night is the only different thing I did.  Could it be related? [/INST] Well smoking hookah can defiantly harm your lungs but difficult to say whether it has harmed your TMJ joint or teeth. You can have a muscle spasm in that area or could also have TMJ problem which could be having an inflammation around the joint. But as you are also suggesting it pains you when you chew there can be dental reason to get a specific X-ray of the particular teeth u feel the pain also get an OPG cozy our wisdom tooth can also be the culprit because such vague pain is also seen in impacted third molars. Just get your radiographs done and see your dentist scorecards Chat Doctor.  </s>
