What Causes Stomach Hardness And Bloating?

My 8 year old granddaughters stomach looks bloated & is hard. She is complaining of cramps on the right side, down low. She kind of pulled away if you push on her right side. I don t think she is telling us everything because she is afraid she will have to go to the doctor. She doesn t have a temperature. She had a bowel movement today and it was soft but not diahrrea.mill
