Owwy!!!

[Starry]

While placing some corals and doing tank maint. today my upper forarm briefly rested on my branching hammer coral. As my arm moved away It felt as if I was pulling away from something slightly sticky. Didnt hurt then, but it sure does now! Feels like my arm got dipped in boiling water. Forearm has several large welts and a few of what look like pimples. Vinager is helping a little. Lesson learned, WEAR GLOVES! akward or not.
