Hi, im shaking, with really bad stomach ache. I feel im getting a fever. I wasnt feeling too hungry today but i had some breakfast and cofee and I was fine, i didnt have lunch but then forced myself to have a brokoli salad at around 5 pm after about an hour i started getting hot and cold flushes and stomach ache and its just getting worse.Its not my time for my period, I did get like this once but that time about a month and a half ago i had my period too. I just had sever stomach ache, fever, I was shaking, getting cold and hot flushes like I am now. It eventualy went away, but it took a whole day. My gp then gave me mefanamic acid 500mg but I took it now and its not really helping. What could it be? And what would help?
