My 12 year old has had ear drainage for about 4 months. Pediatrician found nothing. Developed a sinus infection four weeks ago, resolved with Biaxin. One week later began a persistent headache that won t quit; ear drainage continues. Biaxin for 2 weeks did nothing. No OTC product worked for pain, antihistamine, anti-inflammatory - nothing. Seen by pediatrician 3x, urgent care center 1x, ENT did facial CT scan and cleared of any sinus infections, Emergency Room did Full Brain CT and again negative. Saw a neurologist who put her on Clindamycin, Elavil and Imitrex. Had improvement for a few days, but headache back again and is feeling loopy from Elavil. Imitrex didn t work, and got some relief from Aleve but is transitory. We are awaiting MRI scan, but since lab sent us home following the test with a disc copy of the scan, we feel that will probably also be negative. Never had a fever through all this. Will be seeing allergist and dentist next week - maybe it s rhinitis, or maybe it s impacted wisdom teeth? I m at my wit s end and spend my sleepless nights researching the internet. What do you think of all this?
