I want to know, can this contribute to feeling tingly or numbing feelings down the left side of my fingers? I know for a fact it can for your arm and leg, as an Anxiety Councellor had told me.

Or can it also be from sitting for a long period of time, which I heard can also lead to your whole left side feeling like that. (Studying) No exercise or movement, hardly.

Can you give me advice on my situation and how to prevent these feelings in my fingers.

Thank you,
