Talk to Pediatrician on Pediatrics Gastro Intestinal Problem

My daughter age 10 had one loose motion in afternoon. Later she ate rice khichrii and immediately afterwards she felt vomit but couldn't. She says she feels stomach spasms. She has such issue like every month once or twice. Especially on week ends. Has phlegm and cough but phlegm stuck not coming out. Got checked twice in last few years by gastrkenterologists but everything was normal. Kindly advise any medicines that may help or any tests like stool... We normally give enflor sachet and banana...
