Hi, sharp pain around the navel that radiates upward along with diarrhoea coming in waves could be due to intestinal spasms, gastroenteritis, IBS, or a gut infection. At 64, it's also important to rule out anything related to the large intestine or gallbladder.
For now, stay well hydrated, have light easy-to-digest food, and avoid spicy or oily meals. If the pain is worsening or the diarrhoea is severe, please don't delay getting evaluated.
