Question: I have noticed a horizontal white area in the center of my nails and a red line above the half moon. I am not numb or in pain. (I have had breathing problems since May but they can't figure it out. I have had all tests). Is it normal for nails to look like this?

Brief Answer:
Leuconychia striata most probably

Detailed Answer:

Welcome to HCM....

I read history and saw the photos,after that I could conclude that most probably you may be having leuconychia striata.

Leukonychia striata is a condition in which horizontal white streaks occur on the nail plate. And they are the result of abnormal keratinization of the nail plate.

Exact cause is not known,but following points may be considered...

-The tendency to develop leukonychia striata may be there which is inherited in an autosomal dominant fashion.
-vigorous manicuring,
-wide variety of systemic illnesses.

It is found that in many patients there is no obvious cause and the white streaks resolve spontaneously.

In your case the leuconychia striata would have occurred due to multiple systemic diseases you suffer. However, it is not bothersome,so,do not worry. They might clear in few weeks to few months. No particular treatment is needed.

I hope this would have satisfied.

Hi.My fingernails have white spots on them and my toenails have white areas on them. My toenails, when rubbed over, flake. I have lumps of dandruff, mostly in the middle of the back of my head. And a flakey spot at my widows peek. These spots itch and when scratched, they bleed. My distance vision is getting worse, to the point I wear my glasses all of the time for distance, but am not in need for up close vision.
I am a 45 year old female.

White markings on my toe nails. Cannot feel to touch, they are not raised, just scattered, white blemishes. I usually use polish to hide them. I also probably have fungal infection under the nail on one foot, but the white markings are on all my toe nails. ???

I have been taking accutane for about 2½ months now, and my nails , especially my roots, are beginning to take on a faint yellowish color. Is it connected? Is it serious? I read somewhere that yellow nails could be a symptome of liver problems, and as accutane, or isotretinoin actavis, is disposed through the liver, I m kind of concerned.
