theres a little black spot on my foot thats kind of swollen and hurts to walk on, i think its either a really deep peice of glass or some kind of mole. do moles get irritated when they're on your feet?
I don't think it's a mole on the bottom of your foot, you could have a glass splinter or shard. It might be a thorn. Was the spot there before or did it happen after barefooting around somewhere with glass or thorns. You might have to remove it if it's glass. Sometimes a thorn will push itself out or the body will begin to destroy it. I'd clean it up real well and put neosporin on it and see how it is after some time. like a day or so.
the same thing happened last year but it stopped hurting when i stopped barefooting for the winter, you'd think my body would force it out after awhile
that happened to me once.... actually in my own apartment... must've gotten glass stuck in my work shoes and it fell out at home..... but i got a big shard in my foot and while pulling it out it cracked in half.... so a piece was deeper in there.. so i just grabbed a razor blade and bit my lip while i cut a little deeper so i could pull it out..... was waaaaaay better after that...
Try soaking your foot for a bit in water, then see if you can find it with a pair of tweezers and/or a needle (sharp nosed tweezers are a must-have for barefooters, splinters aren't that common but they do happen). Your skin will be softer and you'll do less damage than if you try to dig it out dry. Also, I've never tried this but heard the suggestion on the SBL list, use a glass bottle that is first warmed, then applied to the skin over the splinter or thorn and cooled, creating suction to pull out the offending object. Other suction devices may work as well; there's a tiny vacuum pump for use on insect bites, to withdraw the venom, that may work on tiny slivers or tiny thorns.
I can't believe you used a razor on your foot although, i have used scissors so............ Break the skin more if you can then put a finger either side of the wound and push down under the glass then up. If it's that deep you need to cut the skin a lot though you need to go to the docs, makes sense even if you might not be bothered. You don't want an infection.
Don't cut until you've tried with tweezers & needle or pin! Never do more additional damage than you have to. I've never used a razor, I've cut off a little of the very thick callouses with nail scissors though (not digging with the points, but cutting across with the bent scissors, just taking a bit of the top layer off). Could also use a foot file but I wouldn't take down the callouses more than absolutely necessary either.
It could be a blood blister, I've had those on my feet before. With those you just have to get them open and get all the goop out.
