Perforated eardrum, playing rugby, someone mistook my head for the ball. Easy mistake to make!
No pain, just sounded like i'd not cleared my left ears also everytime I tried the Valsalva (sp?) technique, my ear would whistle!
6 weeks off flying, no contact sports, no swimming etc and a course of preventitive anti-biotics, no probs since. (4 years plus)
Was told that larger tears would require surgery.
Hope this helps.
