I recently traveled to Houston from Pittsburgh this weekend. The flights were fine, some rough turbulence on the way down and coming back saw some nice cloud structure. Anyway when we were descending into PIT I got a sharp pain behind my ears and my right here still hasn't "popped." When I went to our school's health services the nurse looked in my ear and saw blood against my ear drum...anyone know why the descent would have caused such a reaction? I've flown a number of times and this is the first time I've had physical problems from descent.
