You are most likely suffering from acute viral gastroenteritis
Presence of loose stools, gargling sounds in stomach, body ache
suggests the diagnosis.
You should consult with internal medicine specialist and should go for thorough check up.
Although cause of gastroenteritis appears to be viral yet you should take complete antibiotic therapy, antispasmodics, probiotics.
You should avoid milk and all milk products.
Maintain your hydration status.
Take oral rehydration solutions along with potassium rich supplements.
