Symptoms of Common Foot Problems
A normal nail bed is pink and smooth. Anything other than that may be a sign of a serious medical condition, Reynolds says.
Are your nails brown or black?
Are they green?
This might be a bacterial or fungal infection caused by trauma to the nail. The tint could be from trapped fluid or pus underneath the nail.
Are there horizontal ridges?
Bumpy lines that run across the nail may be an indication of chronic eczema on the skin under or around the toenail.
Are there vertical ridges?
Some people with rheumatoid arthritis or problems with circulation have lines running along the length of their toenails.
