Sorry, second metacarpel. My mistake.
Was a nice crack straight from the thumb side through to about the middle of the knuckle. Add in skin off palm, big gaping wounds across knuckle and swelling making my hand looking like a boxing glove. An immunity to local anaesthetic and needing stitches with no numbness to my hand. Not my best work considering it was self inflicted.
Trapped nerve? Still haven't found out about my finger numbness issue, especially when sleeping. If it's a trapped nerve in my finger then my gp will probably check my knee reflex to find it. Not particularly impressed by GPs who diagnose with the help of patients.co.uk!
Sorry if that's denigrating anyone's profession. I mean no respect but the gatekeeper effect is only going to get worse. Not least as I'm cruising towards my 50s so more things might go wrong if I don't keep on with my healthy ways.
