My 11 year old daughter has had a really bad tummy ache for around 4 days she has also got a bad cold. She says it feels better when she lays on her front but she says it still hurts. She also stretchs then curls up really small when she says it hurts the most.
HiS he needs to see a doctor right away since this could be appendicitis.  Any stomach pain lasting this long needs an evaluation
