I've had a strange thing happen a few times in the last many months. The first time it happened was when the kids and I were on our way home from Houston after their surgery. We were staying at Susan's house. The kids and I all ended up sleeping in the media room on sofas and chairs. Not that Susan didn't provide us each with a lovely bedroom, but we layed down to watch TV and just never got up. I joked that maybe we'd gotten to used to sleeping in the same room after staying in hotels so often!
Anyway, it really wasn't cold and I had a very heavy blanket over me. I should of been warm but instead I was freezing and never warmed up all night. I just thought it was a fluke but lately it has happened a few more times. I get so cold it honestly feels like there is ice in my veins. Sort of the reverse of a hot flash!
I know about being freezing when starting to get a Crohn's attack, This is different. While blankets make my skin warm, inside I can't warm up. I have no idea what causes it.
