There is a sticky here with sting info I beleive. I printed off a copy of necessary info and put it somewhere I won't forget so if I get a bad sting I have good info to hand the ER doc. Lots of ER's don't know how to react to such a thing when Rays aren't native to the region. A true sting is supposedly way up there in the pain levels, and even worse than that is the long lasting side effects. There is a good reason I don't hand feed or play with my Rays no matter the size. Not worth it. Jamie Barrett got it bad about a year ago. A whole portion of his had rotted off.
