Tummy Ache

I have the worst tummy ache ever since last Thursday. Not sure whether I contracted e-Coli. None that I am happy about. My tummy is just isnt happy at all. In fact it aches like crazy. The doctor says it is gastric since I am gripped with a terrible pain.. I forgot to let her know that the pain is also burning like. How I hate it... need to forgo drinking the orange juice. I hate it. I just want to drink the orange juice. No sure why... I have a crazy thrist.
