Posts like this are invaluable to less experienced divers like me, I'd never heard of HPNS til a few pages into this thread so went and educated myself, now I've learnt that compression arthralgia kicks in at depths I've already done and that rushing to shorten bottom time makes it worse. Time to find a decent book on the effects of diving deep(ish) I think. Thanks!
Uhh, you've been to depths that compression arthralgia can kick in but had never heard of HPNS before?? No offense, but that's kind of scary.
