You might cringe at the thought of having a fungal or yeast infection. The concept might feel icky. The reality, however, is that many types of fungi live on the skin all the time, even though you can't see them. Most of the time, these fungi don't cause any problems, but sometimes a fungus will change and cause an infection. These are some of the more common fungal and yeast infections that people experience.
Because fungal spores can remain viable for months in these environments, frequent exposure can increase the risk of infection (and re-infection). Fungal spores can be picked up in many ways – such as wearing shoes that harbour the organism, by walking barefoot in areas where the fungus is prevalent (especially public showers and locker rooms), by wearing wet shoes or socks for long periods, through previous injury to the toe or toenail that opens a path for easy entry of the fungus, or by wearing improperly-fitting shoes.
Red or black nails due to a hematoma, or blood under the nail, usually occur from trauma (like whacking yourself on the thumb with a hammer). The discolored area will grow out with the nail and be trimmed off as you trim your nails. If you have a black spot under your nail that was not caused by trauma, you may want to see a dermatologist or a podiatrist if it involves a toenail to make sure it is not melanoma (a type of skin cancer associated with pigmented cells). A simple biopsy can rule out malignancy (cancer).
You can also try itraconazole (Sporanox), which is usually prescribed with a dose of 200 mg a day for 12 weeks. Side effects can include nausea, rash, or liver enzyme abnormalities. It should not be used if you have liver issues. Sporanox also has interactions with over 170 different drugs such as Vicodin and Prograf. Check with your doctor to ensure any medication you are taking does not interfere with it.
One of the best remedies for toenail fungus, apple cider vinegar can be used topically, internally, or both. Mix one part ACV and one part Epsom salts with six parts hot water. Let the water cool so that it is still warm to the touch, but not so hot as to be damaging to your skin. Soak feet up to twice daily for at least thirty minutes to kill fungus. Mix two tablespoons of organic apple cider vinegar with eight ounces of warm water and add a teaspoon of honey to sweeten the beverage.
Toenail fungus is an infection that gets in through cracks in your nail or cuts in your skin. It can make your toenail change color or get thicker. It can also hurt. Because toes are often warm and damp, fungus grows well there. Different kinds of fungi and sometimes yeast affect different parts of the nail. Left untreated, an infection could spread to other toenails, skin, or even your fingernails.
