Vertical brown line on nail?

[MarkyMark123]

Does anyone know the cause of this? Or what might cause it? Haven’t stumped my toe and it’s only on this nail ?

Are you taking any medication ?

[MarkyMark123 in reply to Galen70]

No. Why you ask?

[Galen70 in reply to MarkyMark123]

because some medicines can cause nail colour changes

This is likely what you are experiencing. The line on your nail isn’t necessarily dangerous or a sign of disease, but it does indicate you really need to be absorbing all of your nutrients properly.

Consider seeing a doctor for now (and definitely a nutritionist) so you can develop a health plan that will make sure the only side effect you ever experience is the line on your nail.

It’s not a ridge it seams to be a line under the nail

It could from a medication that has a dye in it. Have you taken phenazopyridine? That is one example of a medication that can distribute orange/red dye to tissues in the body. Sometimes you can even see the hue of the medication in the whites of the eyes.

I hope you figure out your health mystery. Take care.
