Hi , I m a 29 years old mother of 3yr old son.My height is 5.4 and weight is 54kgs, last night I had unstoppable shivering with high fever and pain in the upper stomach area, the shivering was not in control at all, I have had this fever and shivering 6yrs ago once and also once when I was newly married (7yrs ago), but these days I have stomach pain also with it. Please help me know the reason and things to avoid it happen again.
