The Strangest Thing...

Yesterday my MIL & other family members tried their hardest to alleviate my Cabin Fever & frustration, which was very nice. I managed a quick trip to the hardware store (which was useless cause they didn't have the part I was looking for, which confused me because they sold the original big contraption to me), and a stop in at the Ice Cream shop. My first time in a Coldstone...yum. I've had it before (the Mr stops by and buys some for me sometimes), but have never actually been inside one. It was yummy.
Later in the evening, I discovered a red splotch on my arm, and didn't really think anything of it (other than to note it) because I had been snuggling with a snoozing H on my lap.
This morning I woke up, woke up D, and hopped into the shower while he got himself ready. I crawled out, and while drying off, I notice this...on my legs.
So, I kinda started freaking out. I came downstairs, where it was nice a bright (I have my bedroom and the boys' bedroom blacked out so we can sleep better), and saw it went all the way down to my feet. I had no trouble breathing, and it wasn't itchy, so WTF?!?!
Well, a calmly placed phone call (I made the Mr do it cause I was having a tough time keeping calm) to the MIL brought her over ASAP so she could watch H while the Mr took me to the Dr. Obviously, it was an allergic reaction to something, but I have no clue what it was. I had filled a prescrip from my last visit (Thurs, I believe) from them, but I'm the type who fills them out in case I need them, and usually end up leaving them on the shelf. No new foods, no new detergents, the only new thing in the house that I could think of, was our new Range Hood, and the clothing we bought from Goodwill yesterday. Frack. So, I filled the prescrip, and took my first round, then took H for his nap. BIG mistake. Weird F*in dreams man, I won't be doing that again.
Apparently, it'll get rid of the rash after x amount of days, but I won't have any clue what gave me the damned rash to begin with. Oh Well, at least I know I'm not going to die.
Did I mention I'm as sore as if I ran a marathon?! It's crazy!! My knees, hips, joints, arms and forearms are all achy, and I feel just plain tired. Talk about yuck. I hope it passes quickly.
