Stomach flu? food poisoning? what can it be? HELP

Sunday night I had rotisserie chicken from walmart super center with my fiance. The only difference on what we ate was a macaroni salad she had from walmart and I had a baked potato from home. That night when she went to the bathroom she had slight diarrhea. The next day she woke up fine, but around 11AM started having a real bad headache. At 1PM we ate lunch. Some left over rotisserie chicken, she had it with corn and I had it with peas. After that, hour and a half later she was in the bathroom. At around 7PM diarrhea had started, she had a headche, layed down, and by 8PM was throwing up, she threw up about 6 times puking everything she ate plus more (nothing but water)
She was real bad all day yesterday (Tuesday) and over night she complained all night, couldn't sleep from headache, and mostly stomach pain. She has been taking Emetrol recommended by the pharmacist since she doesn't keep no food down. She doesn't have medical insurance at the moment so hasn't wanted to see a doctor to avoid a big hospital bill.
Could she have gotten food poisoning? Stomach flu?
I don't think pregnant because she has diarrhea and I mean is in the bathroom every 5 min just letting out liquids.
Any advice, recommendations, on what she can try to eat, she so weak since we has not ate nothing, but I don't want to give her anything heavy. So far she has tried drinking gatorade, eating jello... today she feels slightly better (Wednesday 11:30AM)
Thanks in advance.

Thanks everyone, I will definately try your advices and if she's not better by the end of the week I'm taking her to ER

anything she can take for the headache? her head hurts a lot!!!

This could be either one. The abdominal pains from food poisoning though will knock you on your @$$ and fever and or sweating a lot tends to go with it. A mild case will not necessarily act like that though. It can give you severe diarrhea and nausea which you explained she has. And whether this is food poisoning or a stomach bug, it sounds like the body is fighting like hell to get rid of it. (And it's working.)

Make sure she has got plenty of fluids because she could become dehydrated. Gatorade and flat ginger ale or cola(stir it!) are best, flat soda will help to settle the stomach. Also the stomach will continue to feel unsettled unless you put something in it. Wheat crackers and sourdough pretzels will sop up all the crap liquids in her stomach and help her to feel less queasy. Other crackers and stuff will work, but not as well. This will also help her to actually stop puking. (I learned this trick from being a drunk and it works like a charm LOL)

If she simply will not stop puking or diarrhea, go to the pharmacist and ask for charcoal that you drink. This is usually sold behind the counter, and you do not need a prescription for it. (If a Dr. believes she might have food poisioning, this will be the likely course of action anyway.) This stuff is gross, but it works. You'll have to tell her to chug it quickly just to get it down there. What it does in the stomach is absorb everything (similar to those crackers I told you about) so that the body can pass it all out the backdoor. It will also absorb poison. Charcoal has phenominal absorption properties, and that is why it's used. It's used to pump people's stomachs from overdosing. (Don't even think about using Kingsford, too many chemical additives.)

If you girlfriend still has diarrhea or a high fever after a few days, she blacks out, or sudden possible problem with heart (tightening of chest, sharp pains) suck it up and take her to the E/R and worry about the bill later. Cry about the bill and say you can't afford it......it is possible that you can be covered by Medicaid (welfare) for the incident.

Oh yeah, and give her lots of kisses on the forehead. I hope she gets better, like today.

**Alleve is awesome for tough headaches, and it does not bother *my* stomach anyway**

give one tablespoon of gator-aid per hour. watch out for signs of d-hydration (sweats the quickly stops, dizzy, etc.) because she has lost a lot of fluids. if she becomes de hydrated, you have to take her to the hospital for an IV. try milk of magnesia (found at any drug store) for the stomach pain.

TO CLEAR HER DIGESTIVE TRACK GET HER A QUART OF DANNON FRENCH VANILLA ALL NATURAL YOGURT AND EAT I QUART A DAY TO PUT GOOD BACTERIA BACK IN THE SYSTEM . ANY TIME YOU HAVE DIARRHEA THE BAD BACTERIA HAVE TAKEN OVER -----AND A QUART OF THE ALL NATURAL FRENCH VANILLA DANNON WILL CLEAN IT OUT ---AND DON'T USE ANY OTHER TYPE WITH FRUIT OF ARTIFUSAL ( SP ?) SWEETNERS AS THEY WON'T WORK AS WELL . DO THIS FOR 3 - 4 DAYS TO GET SYSTEM TO WORKING AND STAY OFF MEDS. AS THEY ARE ALSO PART OF THE PROBLEM .
