Welcome to Kb.
I do get pins and needles etc in my fingers while riding, but I wriggle my fingers as I ride, and it seems to fade away

[Subike]

was getting this at the beginning of summer
found it was worse after a days work or when I had not had a good meal.
I also altered the angle of my bars so I was not leaning on them as much, this plus relaxing more on the bike has reduced the sensation.
I have carpel tunnel (sp?) syndrome myself from over working my hands, so that is of no help.
White finger I get in one hand, the only hand injury, cut tendon, is the finger that gives the problem.
Heated hand grips have also eased the problem on long trips
