Important question here.?

Two years back my family and I were at the river, in a cove we were swimming in I spotted a $20 dollar bill and dove for it very quickly and came up just as fast to a HUGE pain in my head! it lasted for the longest time and got worse as we drove down this really long hill. I didn't go the hospital like I should of and, now two years later I'm still having some of the affects when I'm sick or just getting done being sick coming down my mountain it still feels like is going to exploded......anyways my question is if I did get "the bends" or something like that could I go skydiving and be alright? or would my head pop off?? I'm concerned about now that I want to sky dive. any advice would help thank you:)
