Wow- good thing you caught it!
My son's cousin had something similar (his stomach actually kinked) and he didn't know there was anything wrong until there was pain and his mom figured it was just a tummy ache (as he was prone to have) and finally she took him to the hospital and they found out the kink had turned some tissue gangrenous and they had to move quick!
You are very lucky, my dear!
Now you can relax for a little bit while you get better and play with us!!
