Talk to Pediatric Gastroenterologist on Pediatric Gastroenterology And Neurology

Assalamu alaykum WA rahmatullah WA barakatuhu. Son age 7 has some issue. He keeps going to toilet after every few minutes. He feels need to go then keeps sitting there. No diarrhea etc. Not sure if it's some gastroenterology issue or some psychiatric/neurology issue. We are worried because around a year ago he had same issue of incomplete evacuation feeling urge to go to toilet with urgency, but later he developed behavioral neurology/psychiatry issues like used to start weeping. Over sensitive behavior etc.we think that From last few days again he's getting over sensitive and starts weeping without any serious reasons. kindly advise any tests if needed. JazakAllah
