Re: Is this Carpal Tunnel?
It does sound as though it could be CTS, especially since you're not experiencing pain and numbness in your pinkie finger and since you got relief when you weren't working. If you do any type of repetative work using your hands a lot, you're definitely at risk for developing CTS.
I hope you get some answers from your doctor and some relief soon.
By the way, congratulations on your baby son.
