Hi I'm a 33year old female & I'm quite worried. Last night I had severe upper abdominal pain (central under my rib cage) its was really bad & I was also vomiting with the pain. At first I thought it was a bad case of trapped wind, but it seemed to ease a little after each time I was sick. The pain was so bad if it had been lower I would of sworn I was in labour. Please does anyone know what this could be?
