I have a dark spot on my toenail, what is it?

You should see a doctor to be sure. You have not given enough details about them, how long you've had them, your overall health, etc., and only a doctor who sees them can really tell you. It's really important that you see doctor if you are a diabetic! For a diabetic, any foot problems, even seemingly minor ones like this, can lead to more serious complications.\n\nThe spots might be bruises from shoes, especially if you are walking/running in them a lot. When I was a marathon runner, I got dark spots on each of my big toenails. I went to a doctor and he said that they were brusises under the nailbed. They were caused by the toes of the running shoes hitting those spots over and over. They were already damaged, so he told me to try a different pair of shoes and/or run less. The spots stayed there a very long time. The nails "lifted" and I had to be very careful to keep them dry and use a solution to prevent nail fungus from growing under them. I did as directed by my Dr. and did not get nail fungus, but one of the nails eventually lifted off completely-gone! It took a long time (several months) to grow back-it wasn't pretty!\n\nIf your nails are also yellowish, you may already have nailfungus too. Best to see a doctor as soon as possible for a proper diagnosis.

To protect the edges of our toes. The area where the toenail is located is a place where the toe contcts objects the most. If we didn't have toenails or fingernails, the tips of our toes and fingers would be continuously bleeding and injured.

Nope, I don’t have dark spots on my tongue … LOL. But you better not laugh it off if you have spots or patches on your tongue because it could be a medical condition. As you may not find your answer here, I suggest you see a doctor to get his expert opinion.

Yes, the use of a salve or a lotion containing hydroquinone. Place directly on the dark spot using a q-tip and in a few days it will lighten. It blocks the production of melatonin, which causes the darkened spots. Can be purchases at some drug stores as a lightening salve. Key ingredient    approximately 1-3%  hydroquinone.

It could be several things, really. It could be an infected hair follicle, a wart, a really determined pimple, or many other things. Does it bleed? Does it itch? Is it painful when you leave it alone? \n\nDon't pick at it. See your dermatologist. Good luck. :)

My dad always said it was the amount of lies you told...\n\nBut really, they’re called “leukonychia” and are very common. Most of the time the white spots simply are a sign of some past injury to the base of your nails or an allergy to nail polish.\n\nA lot of people say that it has to do with a calcium deficiency or zinc deficiency, but this isn't true.

Get a pedicure where they can clean/scrape the surface of the nails a little, and don't apply any nail polish after that. Just let the nails "air". Apparently, the lack of oxygen causes the nails to yellow.

Your nails have to have oxygen because the under lying part is still alive.  The top is dead cells.  Without the oxygen it can get fungus or infections.

It sounds like you have an ingrown toenail and the only cure for that is to have it removed.  I don't know what color it is, but if it has gotten thick and yellow, then you probably also have a fungus infection in the nail.  If the nail is gray and the toe around it is bright honking red, then there is a chance that you have a staph infection.  Either way, a trip to the doctor is in order, unless you can pull it out yourself and have access to antibiotics.  Good luck.

IF you have streaks that are darker/lighter running up your ankle, that is a sure sign of bacterial infection. Bug/spider bites can give a serious infection. Sounds as if you may have brown recluse spiders in your home. Get to a doctor immediately...this is nothing to play around with. Make sure before you put your shoes on that you shake them out very well...bang them on the floor, etc.  Some spiders, including recluse and black widows, love shoes to build webs in.

Yellow toenails is an indicator that your body is out of ph balance.\n\nGet the nutrition basics down and your bodies signal will not have been in vain.\n\nDrinking 6-8 glasses of distilled water with a pinch of unrefined sea salt will help your toes and may cure what may have been coming down the line.\nhttp://www.curezone.com/foods/watercure.asp\n\nWell fitting shoes could help.\n\nSoaking your feet in Epsom Salts could help.\n\nSoaking your feet in apple cider vinegar(the cheap stuff from the grocery store) will help\n\nSoaking your feet in dilluted lemon juice will help\n\nDrinking Lemon Water will help\n\nA drop of Wild Oregano Oil on each nail could zap fungus.\n\nColloidal Silver externally could help.\n\nSunlight could help...let the sun shine in. Vitamin D from sunlight and not from mucous milk could help significantly. \n\nEating more raw fruits and vegetables will help\n\nI would drink a daily drink of half unsweetened apple juice/grape juice with a tablespoon of raw unfiltered apple cider vinegar, a dash of turmeric, cinnamon, turmeric, and one drop of wild oregano oil. When the yellowing fades, I would continue the drink but quit using the oregano oil.\n\nhttp://curezone.com/blogs/f.asp?f=179&t=32541\nhttp://curezone.com/blogs/f.asp?f=740&t=32560\nhttp://curezone.com/blogs/f.asp?f=172&t=32588\nhttp://curezone.com/blogs/f.asp?f=605&t=30517\n\nIt is good that you are picking up on your bodies cues to hydrate itself and give your body good circulation. Do what works for you and stick with it to achieve

Could be both fungus and stain.  Arcrylic nails harbor all sorts of germs.  Nurses in some hospitals are banded from wearing them.\nConsult with your doctor.  You don't want to go around spreading disease.

Try a doctor, the nail salon will just "solve the problem" by putting some nail polish on it or something

This can also be a zinc deficiency. No matter what kind of deficency it is, just take a good multivitamin.\n\n Make sure that you take a good multivitamin, and in a few weeks check the tops of your nails again, as it takes a few weeks for the nails to grow out.\n\nIf you're still having problems after a few weeks/months with your nails go to your doctor about it, and he can help you with it. \n\nBut it's probably just a nutritional thing.
