It was a pretty nasty cut - he was working, clearing some weeds from behind a drainpipe (in the car park of the social club) and cut his thumb on some broken glass behind there. It was a good week before it started to heal. It looks like it has healed over now, but he keeps getting this pins and needles sensation all up his arm. It happens when he lifts his arm up, ie to drive and I think it's getting quite uncomfortable.
Should he see a doctor? He's not one for going to the doctors generally, and he thinks he's damaged a nerve and it'll just go away, but I'm not so sure. Any thoughts? TIA
