Heat Exhaustion...oh my do my bones hurt

I had a case of heat exhaustion yesterday. I was at a shoot, it was hot and it snuck up on me. I drank a boatload of water all day, but I was horribly overdressed for the hot weather and I didn't park myself in enough shade. I'm fine now, but last night and this morning when I got up, I could barely walk. My hips, SI's and heels were just screaming. I took some ibuprofen this morning and it helped immensely. I've been feeling just fine until then. I went back out to shoot today and while I'm tired, nothing hurts any worse than a normal day out shooting (we do a lot of standing all day).

I could see my muscles screaming from the heat exhaustion, but not my bones. Very strange. Like I said, I'm fine now, but yesterday was just weird.

I've been out in the sun shooting quite a few weekends, no problems, this was out of the blue.

Anyone have any ideas of what I may have missed?

You know, it just occurred to me. I also started my period Friday and it was pretty rough on Saturday. Think that might have contributed to the heat exhaustion? Can't see how that would affect my bones -- I'm reaching here!

I agree with you CA...some days it seems harder in the sun than others, but this really knocked my socks off.
