One of my little toenail has been brown like forever. why? and how to get rid of it?

Onychomycosis: Could be nail fungus. Go to see a local podiatrist in your area. The nail can be cultured and examined microscopically to determine if there is a fungal infection present.

Keep in mind...: The fda has recently come out with a blanket statement that toenail fungus can not be cured. It is "managed" by a number of modalities, but it can always come back in the future. Oral antifungal medicines (lamisil), topical medications (formula 3), laser therapy, surgical removal, homeopathic applications (tea tree oil). Talk to a podiatrist for what will be best and most effective for you.

Bruising: It could be a result of shoe pressure, which can cause bruising under the nail. You have to avoid shoes with tight front.

It all depends.: Toenails on the little toe are subjected to shoe trauma on a regular basis. The result is that they distort, thicken, turn color and become a concern on a regular basis, for some. You can certainly spend a whole lot of time and money treating the problem, with no guarantee that the nail will ever permanently be "cured". Consider having it permanently removed. It looks better even painted.
