Sorry to hear that. Probably hurt like a son-of-a-gun.

I lived outside of Tucson in the desert for 7 years and never got stung or bit by anything. Just watch where you walk and be extremely careful of where you lay or sit down. Be especially on the lookout for small, white scorpions. I've been told their poison is the strongest.

We used to have an exterminator out to spray the foundation of our house every month after we found a white scorpion inside the house. I highly recommend doing that too.
