That's the problem isn't it? Every twinge and creak is a symptom! If you've gone off food though and your feeling your abdomen cramping I would say that sounds good! But then again, is it possible that you weren't eating last week when food made you feel sick and now your tummy is just getting used to food again?
Hope I've not disappointed you but I'm sure you can tell I'm an expert at balancing the symptoms lol! Could be this....or could be that...
I really hope you get your

Good luck!
