Always had problems with my ears as well, but it seems much worse with rapid altitude changes below about 5000. Thats where the greatest change in pressure is. At altitude it seems fine. Slightly changing the subject, but staying with altitude, one of my worries is having an expl.decomm and the effects on teeth. Heard some horror stories about cracked and even disintegrating teeth due to air trapped under the filling. Anyone know if this is true, or just another old war story? I always make a point of telling my 'jaw breaker' I fly whenever I need treatment, just in case.
Cheers
