Toenail Pain [Toenail Fungus, Ingrown Toenails, Discolored Toenails]
Black Spot Under The Toenail[Causes, Home Remedies & Best Treatment]
A black spot under the toenail is usually caused by one of four common problems: #1)Jogger’s Toe, #2)Melanoma, #3)Bacterial Infection or #4)Toenail Fungus.

Look:
- A red toenail generally means fresh blood or a fresh injury. This can be called a toenail hematoma, or fresh blood from repetitive irritation.
- A black toenail is generally more dried blood, that has crested underneath the toenail.
- Very infrequently can a black toenail be something more dangerous like melanoma.
- It is also possible for your toenail to the infected with toenail fungus, this can also then result in rubbing and bleeding after the toenail fungus.
- If there is toenail fungus, this is usually more of a brown or yellow color.

Black Spot Under The Toenail Causes:
There are four common causes that I have seen of a black spot under the big toenail, here they are listened in order from most common to least common:
1) Jogger’s Toe (Subungual Hematoma).
Jogger’s toe is essentially just “overuse toe”.

- The trick with this one is it sneaks up on people without any pain!
- Be aware that you can still have bleeding underneath your toenail and it doesn’t have to be extremely painful.
- For example I just saw a woman had a scary black toenail without any cause.
- But the more I talked to her I realized she bought new shoes and started Zumba classes.
- She was exercising more, had small shoes and was not suffering from any pain!
Diagnosis:
- Sometimes no pain.
- Small shoes.
- New shoes.
- New exercise regimine.
- Heavy running or work.
- Traumatic injury.
- Dropping something on your foot.
- It will grow out over time.
- It will not get bigger over time.

2) Subungual Melamona (Black Streak or Mole).
This is as a result of a mole!
- These can appear underneath your toenail or around the toenail.
- The first step is to keep an eye on these and see if they are getting bigger.
- These can be dangerous, so if they are getting bigger or growing into the skin- go see a podiatrist or foot doctor immediately!

Diagnosis
- No Pain.
- It is getting bigger.
- It has been there a long time.
- No cause for its appearance.
- It may be growing into the tissue.
- See our “Is it dangerous guide?“
3) Pseudomonas Bacterial Infection.
This is different than toenail fungus- this is an bacterial infection.
- This means it comes quick and strong, then gets cured for good once you see a podiatrist.
- This goes against toenail fungus which is very slow and resistant.
- Pseudomonas is a bacteria that loves oxygenated moist environments like wet mud and pond water.
- If you have been around any of these recently and you start getting greenish-black toenails, it may be this!
- You should go see your podiatrist or foot doctor for some antibiotics!
- It can also be confirmed by it’s sweet smelling grape-like odor.
Diagnosis:
- No Pain.
- Greenish-black.
- Appears quickly.
- Sweet, grape-like odor.
- History of swimming in pools or ponds.

- This almost seems counter-intuitive, but when people make a switch to really good supportive shoes that fit properly, there toenail problems almost always get better over the next few months or a year.
