Welcome to HCM.Abdominal pain
and loose motions are indicative of gastrointestinal infection
. I suggest you get a stool examination to rule out cause of infection. Drink lots of water. Get in touch with your GP for antibiotics if infection is confirmed by stool exam. Gastritis
also presents with same picture. I suggest Cap Omez 20 mg thrice daily before food for three days if infection is ruled out.
