My daughter is 15 years old. She has history of constipation and encorporesis since the age of 6 or 7 years. Also she has history of recurrent generalized abdominal pain since that time & her ultrasound at that time normal. She started school 2 weeks back & started to have bloated abdomen associated with vomiting. She had history of bloated abdomen 4 times in the last 2 years during long trips in airplane but this is the second time without being in the airplane. First time associated with impacted stools, enema & blood tests done for her, her blood tests came normal & all the symptoms relieved after enema. The second attack relived alone after lying on her stomach & passed stool. She referred to specialist for further investigations
