Tingling feeli from my elbow to my fingers of my left arm and a numb spot in the middle of my back close to spine....

Elbow numbness: The tingling from your elbow to the fingers (especially if it effects the ring and small fingers) is typical of a condition called cubital tunnel syndrome. This is compression of the ulnar nerve at the elbow. See your primary care provider. Recommend trying a night splint, doing some physical therapy, and taking some anti-inflammatories. The mid back numb spot is likely unrealted to the elbow.
