I have a really tender well sore tummy,

I started noticing it the other day I guess and then today it's quite sore.

If I lean forward to eat, touch my toes etc that sort of bending its really tender.

Could is just be growing pains ? or should I keep an eye on it ?

If I move from the point it stops which implies its muscular right ??

I am a little worried as I had some sever vomiting the other night and also a back massage yesterday where I was lying on pillows, neither of these are bending though except the vomiting of course.

any ideaS?
