Weird Stomach problem please help

I have a weird problem. Last week i started getting cramps in my stomach. The stools were normal but i still had to go 3-4 times. I was down the fever for the next 2 days. After that the fever was gone and i was feeling fine. But everyday since i've been having this feeling of weakness. Then 2 days back i again got a fever of 101 and the next day experienced diarrhea for around 5-6 times. Now the fever has subsided but the feeling of weakness doesn't go away. I somehow feel that this is gonna repeat itself again. I went to a doctor and got a lot of test done. These include stool-r, urine-r,mp, mp antigen test & widal. Nothing came up on any of them. Just the stool test showed that the chemical reaction was acidic. I've been on Nutrolin B plus for some days but it does not seem to help.

Sometimes an ordinary illness can cause diarrhea, and sounds like it's hanging around too long.  Anytime you have fever and diarrhea, it's going to tire you out.  Last time I had the flu, it took me a whole month to get my strength back.  My suggestion is simple, just in case this might be happening, but get a new toothbrush, clean the bathroom spigot handles and toilet pusher, use chlorox wipes to clean the phones, doorknobs, refrigerator handle and other handles, anything you touch all the time.  You just need to fool with that one time, and then forget about it.  To help your digestion do a little better, you need acidophilus for a couple weeks, either Acidophilus milk or Activia yogurt are both at the grocery store.  Take out a little time to rest, too, give yourself a break.  Oh, and drink plenty of water.
