I originally had a fever 9 days ago, followed by projectile vomiting and then diarrhea. The fever & vomiting has dissapeared however I still have dirrahea which has lasted for 1 week. I literally can’t eat anything without me having to go to the toilet. I’m really fed up now, feel weak and feel this is never going to end. What could be the problem and what should I do? I feel I need something to help me clear this up.
