I have just started experiencing numbness, tingling and a heavy feeling in hands and calves.

Yes my fingers on my right hand have been tingling all the time and much worse at night,it's worse too if I'm holding my phone or holding the stearing wheel for too long .

I get it in my hands n feet. I noticed my hands/fingers tingle alot when im driving.

Definitely!!!

Yes hands and especially legs after work or when driving.
