I feel hungry and i keep having cramps in my stomache..And pooing quite a fair bit..(But i thought it was just because that's all i needed-Too go to the toilet ect,ect), but i still feel sick, and i have had a tempurature, for 3 days, felt like this for 3 days, ive eaten, and i still feel like it, and every so often my legs begin to shake... Any idea's why? :/ (I'm 15) and i feel like it now..
