Have them seen.: Nail problems of a long duration are very difficult to treat or even recommend treatment without actually examining them. It is without doubt, best to have them examined by someone who specializes in the treatment of nail diseases.

What cause horizontal ridges in toenails? I have horizontal ridges that sometimes look like another layer on both big toenails. My toenails are dry

Many possibilities: There are many causes of horizontal ridges on nails, including trauma, malnutrition, infections, kidney or liver disease and arsenic poisoning but the fact that is it only on your big toenails makes it unlikely it is serious. See http://www. Md-health. Com/Fingernail-Ridges. Html and check in with your doctor if it spreads to other nails or you other symptoms suggesting some of those conditions.

Usually: They're called Beau's lines. May occur from temporary cessation in toe nail growth. Eg trauma. In cases of malnutrition they can also be found. But if you're otherwise healthy, they are normal.

I have horizontal ridges on my toenails. Is this normal?

A record of health..: Horizontal ridges, as opposed to vertical ridges, could represent a significant change in your over all health. They form for many reasons and can have several different looks. Anything that affects the nail root and its production of normal nail may be responsible. This could include trauma, diet, fever, medications and some systemic disorders. To remove all doubt, consult a specialist.

What does it mean if you have horizontal ridges on your big toenails?

Usually a sign of: An injury, often a minor injury that you may not even recall. Transverse lines usally are similar to rings on a tree--you can identify approximately about when the injury occurred by how much the nail has grown.

My daughter has a slight horizontal ridge on one toenail and it doesn't hurt nothing happened to the area what could it be?

My daughter has a slight horizontal ridge on one toenail and it doesn't hurt nothing happened to the area what could it be?

Time lines: The young adult toenail grows out at about 1-2 mm/month. If you measure from the nail bed (near cuticle) out to the line, it will give you a timeline for when something disturbed the regular growth of the nail. It has no more significance than that.

? vitamin deficiency: It is difficult to say right now what caused you pain in the Fall (I might need more information regarding the pain). The horizontal and sometimes white ridges could be a sign of vitamin deficiency.

Dryness or other: Could be just drying or iron deficiency or other pathologies. If it is or isn't fungus, your doctor can get a culture/specium to confirm whether it is or not. Try to see aobut your diet as well as lack of certain vitamins and minerals can be seen first in toenails/fingernails and or hair. Good luck.

My doc thinks I have sympathetic reflex dystrophy. Would this explain the horizontal ridges on my big toe and foot becoming cold with elevation?

RSD/ ridges: RSD affects the nerve function. Esp autonomic nerves that control temperature regulation and sweating and swelling. The lines or ridges can be from the swelling increasing or decreasing. See a neurologist or a physical therapist. Aggressive physical therapy to stop the nerve irritation helps. There are also topical and oral meds that can help

I have had this awful chronic (well, many years) horizontal ridging on my second toenails. The cuticle is misshapen also. Causes/cures?

Probably trauma: Repetitive trauma against the second toe from shoegear can cause this. Most times this toe is longer than the two toes in both sides and it will rub or bang against the shoe more than the others causing nail and skin thickening. It could also be dry skin or even heredity.

Ridges on fingernails indicate what? I have vertical ridges on my fingernails and horizonal ridges on my big toenail

Ridges on nails: The vertical ridges may be normal for you or a metabolic problem. The horizontal ridges are usually called "trauma lines" on the toenails and indicate changes in your nail growth pattern at the root level.

I have a black mark on the lower right corner of my pinky toenail on my right foot. It's very small and looks to be horizontal in lgth. What could be?

I have a black mark on the lower right corner of my pinky toenail on my right foot. It's very small and looks to be horizontal in lgth. What could be?

The Black Toe: Subunguinal hematomas (blood under the nail) are caused by shoe friction. Usually the shoe is a little short or the toe box toe shallow. Tumors in toes can happen but very, very rarely. The nail will eventually grow out as normal but in an extensive hemorrhage under the entire nail, the nail will shed. Ignore it.

I've noticed my big toenails have stopped growing and one has turned yellow and has a thick ridge. What is this and what do I do? I play sports a lot

Nail fungus: Unless you had a trauma to this particular nail, this is probably onychmycosis, or nail fungus. Trauma can look similar. There are now both good topical and oral antifungals to clear this up. See your local foot specialist to see what's best for you
