Yeah, that was my problem with drop bars too. I also use Ergon grips now on flat bars. LOL, I'm in IT too, but I'm right handed. The pain with drop bars was in both palms though.
One point I notice is that my left thumb seems to be nearly at full separation point from the hand when on the handlebar...I can't move it very far aft (back) from the bar...my right thumb seems to have more travel. I know hands/wrists are not perfectly symmetrical so differences must be having some effect here. I do wonder if the numbness is circulation related or nerve impingement.
