Patient discussion about nail plate

Q. My nails are black- is it dangerous? Hi, I was diagnosed with colon cancer and now I receive chemotherapy. This morning I found that my nails are brown and blue, and other nails have white lines on them. Is that dangerous? Should go and see a doctor?

A. The chemo can cause several changes in your nail, e.g. make them brittle etc. You can find some more info at : http://www.breastcancer.org/tips/hair_skin_nails/nails.jsp

Q. my guy friend has a very sick looking toe nail, what should he do? its really thick and has ridges, its also dark yellow and it looks to me has thick toe jam too... ugh, he needs your help please!

A. It sounds like Toenail fungus. Symptoms of toenail fungus, which can be caused by several types of fungi, include swelling, yellowing, thickening or crumbling of the nail, streaks or spots down the side of the nail, and even complete loss of the nail. Toenail color can vary from brown or yellow to white with this condition. I suggest your friend goes to see a foot doctor. The doctor might remove as much of the nail as possible by trimming, filing or dissolving it. Medicated nail polish might be prescribed for a localized infection, but a serious infection will likely be treated with a prescription oral antifungal medication. Only in severe cases will surgical removal of the nail be recommended.

Q. what natural cure for toe nail fungus really works?

A. Haven't heard about anything natural that was actually provent in reliable, well controlled trial. Especially since natural medications usually aren't tested in this way, I'm not sure there can be an accurate and true answer for this question.
