What are toenails trying to tell you?

Your toenails tell a lot about your overall health. A fungal infection often causes thickened yellow toenails. Thick, yellow nails also can be a sign of an underlying disease, including lymphedema (swelling related to the lymphatic system), lung problems, psoriasis, or rheumatoid arthritis.

Can your toenails tell you if you have cancer?

In extreme instances, black toenails can be a sign of cancer or liver or kidney disease. Dark streaks underneath the nail can signal a hidden melanoma, a dangerous form of skin cancer. If your toenails are white, you should be tested for anemia.

What do thick toenails indicate?

Toenails that have grown thicker over time likely indicate a fungal infection, also known as onychomycosis. Left untreated, thick toenails can become painful. Prompt treatment is key to curing the nail fungus.

What does cancer of the toe look like?

This is most common in the big toes of your feet. The cancerous cells underneath the nails can look like purple, brown, or black bruises. These also tend to look like dark streaks that grow vertically in the nail. Unlike nail injuries where the nail eventually grows out, these streaks don’t go away if they’re melanoma.

Can your feet show signs of heart disease?

It occurs when plaque forms in the arteries that carry blood from the heart to other parts of the body, including the legs, arms, and torso. While pain in your feet or legs generally does not signal the onset of heart problems, many people aren’t aware of the possibility.

Why do old people’s toenails get so thick?

The growth rate of nails decreases when people get older. This results in thickening because nail cells pile up. The process of nail cells piling up is referred to as onychocytes. Another reason why fingernails don’t thicken as much is their growth rate is smaller than the growth rate of toenails.

What is the white hard stuff under my toenails?

Keratin is a protein that promotes the development of the skin and nails. Nail psoriasis sometimes causes too much keratin to grow under the nail. This overgrowth is called subungual hyperkeratosis. People with hyperkeratosis may notice a white, chalky substance under the nail.

Why is my big toenail discolored?

Nail fungus, also called onychomycosis, is one of the most prevalent causes of toenail discoloration. The most common organism to cause toenail fungus is called dermatophyte. However, mold or yeast can also infect toenails. Dermatophytes grow by eating your body’s keratin.

Why is my big toenail throbbing?

It usually happens if the nail gets crushed in an injury. It can cause symptoms such as intense pain and throbbing as blood collects under the nail. Unless you also have broken bones or damage to the nail bed and/or surrounding tissues, this injury usually isn’t worrisome.
