Ds has been complaining on & off all day of a pain, left side, below waist above thigh, he says it's "inside". This evening it's got worse, I had to give him Calpol for the pain tonight before bed and he's just woken up crying, 5hrs after the first lot of pain relief.
He can walk, doesn't seem to be movement aggravated.
He has been "regular" today, so don't think it's constipation.
Any ideas?
