I have viral /flu symptoms for 5 days. I still have body aches, fever bad cough and sore throat. I now developed diahrea and cramps. Will it pass?

Viral infection. Sounds like you have a viral infection which should pass in a few days. Make sure you drink a lot of fluids (with electrolytes like sports drinks) to prevent dehydration. Should you develop rash, weakness, observe blood in stools or feel much worse, consult your physician.
