Kitten saved from being trapped under wood pile

I might have to bring a stray kitten to the vet. A kitten was trapped under a wood pile for a few days. I heard it meowing but wasn't sure if she just wanted her mom who was eating across the yard, I couldn't see the kitten and it was crying loud so I moved wood pieces and found her/him It's arm was trapped! Now it's swollen but not bleeding. I was hoping the circulation was cut off and it will go back to the same size. Should I Waite. To see if he starts using it.

I would suggest getting the kitten to the vet sooner than later. If the limb does have proper circulation, it could by likely be broken and need tone splinted to heal properly.

Is the paw cool or warm to the touch?

Does the kitten Ty to walk using the limb?

If you are at all able to...bring it to a vet. At the very least, it has to be hungry, dehydrated, and scared.
So sweet of you to save it

So great you've saved this little one 

A vet visit should be your first stop. You need to know about any injuries (including ones you can't see). It will be dehydrated and starving hungry for sure, and will most likely need treating for fleas, worms etc too. Get it checked out ASAP. 

Please come back and let us know what happens - and welcome to TCS   It sounds like you'll fit right in
