What cause shivering,loose motion and nausea? I have been feeling like this last three days, only in afternoon and evening I have been having 4 times loose motion, nausea, but only feeling shivering at night time. If I put cardigan in then I feel better with no shivering, after a while I felt getting the temperature. The shivering goes away after few hours. Then I was having slightly insomnia, last two days ago was having panic attack, is it what causing? I also have IBS but that has calm down after two months.
