Abut 6 weeks ago I got a thorn in my index finger just on the first joint and the end of the thorn snapped off inside. Had a dig round with a needle and thought I'd got it out. Later it seemed to be a part of it left in there, quite far under the skin and painful if pressed or if I picked something up 'wrong'. I had one subsequent go a few days after it went in at digging it out but it was in too deep and I couldn't get to it so I left it to compost/find its own way out.
There now seems to be some sort of callous forming over around where I think the thorn is and movement in the joint is being affected as the skin has lost its elasticity and I haven't got full movement. It's still painful if pressed or when picking things up that press on it (braking on the bike is thankfully unaffected). There's slight redness but doesn't look like there's any infection.
So mtfu or seek medical advice before it finds its way to my heart and I die horribly?
