Do tingling hands and fingers always signify diabeties?

No: Panic attacks, anxiety, nutritional syndromes and certain brain problems can cause peripheral tingling.

Possible neuropathy: Depending on the affected nerves, symptoms of diabetic neuropathy can range from a numbness and tingling sensation, possibly a burning sensation, to an uncomfortable painful sensation of the extremities. Neuropathy may affect your digestive system, urinary tract, blood vessels and the heart. For some people, the symptoms are mild; for others, it can be painful and disabling.
