When I do get tingling whilst pumping, it is in my legs, not my arms. It doesn't happen all the time, and normally stops if I reposition the way I'm sitting. I don't really pump hard or long either, at most 3hg on the gauge, releasing every 15 mins, because I'm prone to red dots. I've been pumping pretty consistently since February this year.
I read somewhere on the Noogleberry forum that 5hg is the target for growth, but I doubt I'll ever get that high. It's not that it hurts, but I know if I go past 3hg I damage my skin and who know what else.

So some people experience this even though they don't over pump, clearly you don't over pump. I use to ignore the numb feeling in my arms and legs but after Jen's post I am a bit concerned.
