What are these bumps on my leg?

It looks more like poison ivy to me. I have it right now :( I'm really allergic to it so it spreads all over my body without me even having to touch it or anything :( Even if it's in the air I can get it, very badly. Right now it's just on my left arm but I can't even rest it on anything, and at night I have to hold it up in the air to prevent it from getting on my bedsheets and stuff :( So yeah it looks more like poison ivy really, it's actually hard to tell because it also resembles a bug bite! Chances are it could be either especially if the cat rubbed up against you. It could have walked through poison ivy, or let in stuff that bit you. See how long the bite lasts before you make any claims of what it might be. I've never seen a chigger bite though, it resembles mosquito bites too but doesnt look like it has the hole in the skin from one.
