Ds - nearly 4, with a genetic condition - seems to have problems with the heat and with extreme cold. Last night when he was asleep, I noticed that he was twitching,and he felt very clammy around his head. I took his temperature (ear thermometer) and it was 35.1 - his skin felt quite cool, but as I say he was clammy with sweat, his pulse also seemed quite fast. He is alaysquite pale, but seemed even paler and i noticed a blue line coming from corner of mouth to chin seemed more noticable than usual. I sat with him and watched and noticed a couple more small jerky movements, his temperature stayed low for about an hour, but the twitching stopped. His temperature is usually around 36.3. Does anyone have any ideas what this could be??
