Thanks all for the feedback. I did a few jumps this weekend with no ill-effects. I took some Clariton(non-drowsy,doctor prescribed) and depressurized(hold nose and blow) right after I was safely under canopy. My ear is still ringing day in/day out, but didn't seem affected by jumping again. Link on post above had some great info. including another skydiver with similar problem. Also researched tinituss a little bit, and one of the causes can be neck/head injury. Maybe that slamming hard opening that has given me some back problems also plays a part in the ear ringing...........Chris
