We’ve seen so many supposed specialists ( paediatricians, 3 cardiologists, rheumatologists, several gastroenterologists) but still trying to get some help for my daughter. She has very bad daily stomach pain, with chronic nausea., slow bowel motility and gastric reflux. We finally found a good cardiologist, who diagnosed POTs and a provisional diagnosis of Supraventricular Tachycardia. Is it worth seeing a neurologist? What tests can they do?
