My little fingers go numb, i have been diagnosed with carpal tunnel but they tell me the little finger is not carpal tunnel?

Your fifth digit: Is the ulnar nerve territory typically affected by pressure or trauma at the cubital tunnel otherwise known as your "funny-bone".

Cubital tunnel: Involvement of the little finger causing numbness and tingling is generally a sign of ulnar nerve involvement. This is also known as cubital tunnel syndrome. All the best.

Ulnar tunnel: See a hand surgeon for examination and possibly EMG if uncertain.

CTS...: Depends on how you were diagnosed with carpal tunnel - clinically or by emg/nerve conduction study, the latter can detect whether there is any ulnar nerve entrapment.
