I am experiencing finger tingling (quality: localized to little finger, localized to thumb, localized to index finger) .

So it sounds like: you have tingling of at least 3 of your fingers. One of the most common causes of finger tingling is carpal tunnel syndrome or compression of the median nerve at the wrist. But this typically just causes numbness and tingling of the middle digits. A condition causing more generalized peripheral nerve symptoms or peripheral neuropathy is less common in fingers than toes. Need Doc evaluation...
