<s>[INST] hi Dr. my 9 year old boy never had ear pain but after a long flight, 4 hours later he complained of severe ear pain on both ears, a day later he hurts through the jaw and throat more on the right side. His pain reduces to about 3 out of 10 after a dose of children s Advil. ,Four hours later he starts crying again. Please, help me . what is going on so that l can help him better. Is the airplane the cause ? [/INST] Hi, There might have been some amount of Middle ear discomfort from which he is taking some time to recover. If he is not getting better with Advil than I suggest that you use promethazine which is a prescription Chat Doctor.  At the same time now you need to get him evaluated by a physician by endoscopy if he has got any infection. Hope I have answered your query. Let me know if I can assist you further.  </s>
