I am experiencing numbness of my thumb and index finger (left hand), and a feeling of an electrical storm in my left arm, for the past 8 days, or so. A pronounced pain in the area between the scapula and spine (C7 to T3 region). I am male, 57 years of age, fairly fit (gym 3 to 5 days per week). Is spend considerable hours at my desk in front of computer.
