welcome to HCM,
as per the details u have submitted,
It seems you are having DYSENTARY/ BACTERIAL DIARRAHEA..
So i advise you to consult a near by physician and have done the following tests,
1. complete blood picture
2. stool analysis
u will suffer from dehydration
, if the problem persists . so i advise u to go to near by clinic and check your blood pressure also..
until then , keep taking ORS
hope this will help u...
