Much more active. Lately I have been sweeping my deck and front pathway and power washing same. This is much more physical activity than is usual for me. So far my fingers are tingly but not numb. The arm in question is my left and I am right handed. I don't really notice any weakness but the numbness & tingling is not constant but it happens several times a day while I'm up. Don't notice it when I

Brief Answer:
Herniated disc disease of cervical spine.
Detailed Answer:
Welcome back and thanks for the clarifications.
In this case, in my opinion, two are the main conditions that is necessary to be considered:
1. cervical spine herniated disc disease
2.low vitamin B12 levels
It is necessary to measure blood levels of vitamin B12 and to have imaging studies of your cervical spine done ( MRI ) in order to achieve a correct diagnosis.
Discuss with your primary care Doctor about these tests to be ordered.
Hope I helped you.
