Can someone tell me what has caused ridged half moons about half way on all my fingernails?

It is a definite ridge you can see and feel half way on all my fingernails. I have had some major health problems and plan to ask my doctor when I see him...........but I was just wondering.Can someone tell me what has caused ridged half moons about half way on all my fingernails?
Both previous answers are great, not going for a BA here. I found similar info when my nails were getting the same type of ';speed bumps';.


Mine have appeared over the years after times of trauma, whether physical or emotional. I was told, and also read up, that most of the abnormalities we find in our nails are just evidence. Evidence of the past, they need to grow out, to go away. (there's no quick fix for them.) The marks or ridges indicate many things. White lines, blotches...


Have to confess I hadn't read both answers in their entirety, but trust it's all there.


I'd also heard the vertical ones , which are more permanent, indicate different, and more lasting damage/trauma.


I think there's info at a website called Dr. Mercola, as well as WebMD.Can someone tell me what has caused ridged half moons about half way on all my fingernails?

Your nail beds are affected by your health and having surgery will affect them. Since you had major surgery 3 monthes ago, the area of your nail beds would be just about halfway grown out now so that's probably what it was from.
