I had a hip dislocation about 8 years ago and am trying sky diving for the very first time next week. I have recovered fully, hpowever, I was wondering if there is anything IS hould worry about as there is a huge difference in pressure and ofcourse the hard landing with the parachute. Please let me know if anybody has tried this. And please note it is not a hip replacement it is a hip dislocation.
