I just shocked my pool several hours ago, what are the risks of swimming in it now?

Chlorine dissipation depends on a number of factors which with that limited information you provided, I can't say. It can be as little as 3 hours to 24 hours or more from unstabilized chlorine shock.

If the chlorine level is still over 3.0, you'll experience itchy skin, burning eyes and hair damage at the least. You can probably kiss your bathing suit's original colour good bye as well. It'll fade out and it may even come to pieces in the next wash.

there are no risks. after about twenty minutes, the pool goes back to normal. my swim coach shocked the pool once, right before we got there after school for high school practice. after we did crunches and sit ups, he made someone get in (even though there was no real risk-- he let the boy go in and be all "adventurous" anyway :P) and "check" if it was electric.

there is no risk after about twenty minutes of shocking the pool.

Check the chlorine level. If it's above normal, do not get in. It's bad for you and you'll smell funny for a couple of days.

By the way, old chlorine and new sweat smell really bad.
