I don't know if it's a fungus, but it is a quarter inch thick and I can't scrape it off!  Could this be a disease; and if so, what kind?

I don't know about your teeth, have you been on an antibiotic lately?  Your fingernail and toenail yellowing could be a sign of fungus but only a Doctor would know for sure which is who you should contact.

it is probably ring worm or mange, you can put some jock itch cream on it and it should clear up in a week

All three of the above could be the correct answer: candida fungus, leukoplakia, or plaque.  My bet is on the fungus but can't tell without seeing it.  You should see a dentist about it.

I would definitely go to a doctor and make sure it isn't something like ringworm.  I guess this is common because wrestlers are in close contact with other people and also the mat.

If it hasn't cleared up already you need to go to the doctor. They will probably put you on some kind of anitbiotics. The infection could of came from the jewlery itself.

If your uncertain it is yeast- you should go see your MD.  \nA yeast infection isn't a big deal- compared to some things it could be.

You either have a rare genetic defect or you have a fungal infection in the nailbeds. Check with your dermatologist.

I think you should go to the doctor. It could be normal mucus but then it could also be a parasite like round worm. Hope it comes out all right.

Depends on the spider.\n\nI'd go see a doctor just so you know what this is for sure. At least it will put you at ease, and it will rule out any possibility that it's something else.

It could be a scab.  I get those once every few years.  Best thing to do is to see or talk to a dentist.

Well Mister, I think you got yourself a staph infection from picking at your lip. This is not uncommon for a staph to relocate from your face area to a nicer climate, your lip. You'd better get to a doctor or an ER to get some antibiotics or?  Good luck let them know why it started, they may have a look at it, it could be an infected hair that's feeding it, it may have to be pulled out.

It could be an ingrown hair!  Sometimes they have a way of just showing up.  Is it sensitive to touch?  Is it red in color and look infected?  Need more info.  Check out ingrown hairs online and see if it matches up with what you are experiencing.

If it doesn't seem to go away after a few days, I'd suggest you see a dermatologist or general doctor. It could be your skin was just irritated when you got the scrape, if something got on the area and you hadn't cleaned it (I have no idea of course but I'm assuming you were barefoot, if there was fertilizer/chemicals on someones grass and you walked through it, or something like that). Was the scrape really bad, like bleeding, or just sort of red and scratched up? I doubt it's infected, but if you're concerned if it doesn't go away in a day or two, or you have any other new symptoms, definitely just go to a doctor to make sure. You may need an antibiotic. I also think you should put Neosporin on it and see if that helps. Good luck!
