About two months ago I've accidentally stuck my middle finger into broken glass while fixing shattered iPhone screen. Glass had punctured the skin and it bled a little bit, I've used tweezers and needle and tried to make sure there was no glass stuck and left in my finger, I couldn't see any splinters inside the cut, but I got out 1 piece of glass out(just felt it with tweezers), which was around the size of a sugar grain.
Then skin has healed up, and it stopped bothering me for about a month. But for the past 3 weeks my finger doesn't feel right, nearly every day I'd get a weird fuzzy feeling coming from where the skin got punctured coming into the wrist, I wouldn't call it painful, but its there and its really worrying and annoying me. It usually happens when I'm on the laptop, and this finger tip interferes with touch-pad for a while.
I've been to my GP about it, but he just told me to leave it alone, since it doesn't seem to get infected, and it might work its way out eventually.
Is there any way I could get it out or help it get out at this stage?
