Carpal Tunnel Syndrome is compression of the median nerve.
You have several muscles that go through a band (tunnel) which your median nerve uses as well. For whatever reason, if for overuse causing inflammation, structural damage, etc, the median nerve gets compressed you will start to feel tingling sensations.
There are a few tests including Tinel's sign1, Phalens test2
Overuse can lead to pain as well. The solution here is simple, stop using it. Let it rest. Do activities with the hand that aren't repetitive motions.
