Someone posted a link here before that described both a stitch and nausea brought on by exercise. If I find the link I'll post it again.

What I remember is much of what Wahine said and that it is important to do 2 things:

when you feel a stitch coming on, don't let it get up to full strength because a bad one can last for days.

and it's very important to slow down, but if you suddenly stop it is just as bad as if you just keep going hard.

Hugs and butterflies - and extra happy breathing butterflies for your son,
