hi im sarah 20yr old female . i posted a question a couple of days ago , about my concerns over servre stomach/abdominal pains, with that i have also been having stools that run like water' and are a yellowy colour.everytime i eat the littlest food a few hours later im in breath taking pain,and the watery stools shortly follow , as well as a sheer burning sensation while i am passing the watery stool, my stomach makes the most horrific sounds of bubbing and the constant rumble the same as hunger.i am contstantly passing wind , and belching.The pains in my stomach are really bad now that i have to walk bent foward because it hurts to stand up straight,,i am also suffering from headaches and dizzieness to the point if i dont hold onto somthing when i get a dizzie spell i feel i am going to collapse as my vision is blurred for a few seconds. i have been to the docs twice in the past week, first time i went i was prescribed somthing to ease the stomach pains which i found made me feel even sicker, then secondly i have been given antibotics?????? for a food poisioning diagnosis??thats what the doc thinks i have .. i am awaiting 5 days for the results from my stool test to see what is causing the problem.2 very close friends of mine that i work with have both recently gone down with gastroenteritis . im wondering if this could be what i have? . my doc said i carnt have gastroenteritis as i havent been vomiting? ..... my friend at work didnt ither but he had gastroenteritis pretty bad.im just really stuck on what to think or do , i have had the problem for 7 days now with no improvement showing.i am really scared that i could be like this for a long time as it seems even my doctor dosent really know whats wrong with me, i am in constant pain in my stomach, going hot and cold all the time. im really worried.
please advise , i would be very greatful , or has anybody had simular symptoms~? and what the outcome was .
thank you
