Hello there. My three year old son has been complaining of a sore tummy on and off for the last two and a half weeks. Out of the ordinary for him. Has only thrown up once but has had instances where he has been dry reaching. He complains of a sore tummy on and off during the day and will quite often wake him up at night. Have taken him to the Doctors and also the hospital and they both believe it could just be a long standing virus. Have also noticed that he has hiccups quite often and has started with a lot of burping. Any thought or ideas? Thanks a million.
