Just make sure you warm up slowly, and keep checking for twinges or anything that feels weird. I hardly ever tape up these days (unless something cuts me), but as soon as I feel something going, I slap the strappal on. Next session I always start without tape again.
Remember: skin always sticks better than tape on a sloper. Dense is right: just go and hang some friendly holds for a bit, you can still be doing powerful moves. Come back to the crimps when you've healed a bit.
