Hello, your condition may be acute gastroenteritis. The common manifestations of acute gastroenteritis are nausea, vomiting, abdominal distension, diarrhea, watery stool and fever.

Suggestion:

I suggest you take levofloxacin hydrochloride tablets and omeprazole enteric-coated tablets orally to see if it can relieve the symptoms. Pay attention to avoid cold, sticky, spicy, irritating diet, alcohol and tobacco, overeating and so on. Drink plenty of water during illness to prevent dehydration.
