looks plenty like poison oak to me, w/ the scabs caused no doubt from scratching - for me, in bad cases, 4-5 days after exposure the bubbling will expand to immense proportions (say my entire bicep to wrist), will constantly be sloughing off the outer layer of skin, popping and oozing a yellowish/orange goo that hardens quickly - an obvious scar will remain even 3 weeks later
poison oak = an indication that, if god exists, he's most definetly an asshole
