Thanks penguin for all your help xxx
Yes Taz I have ridges,had them for some time but this is the first time they've started to split vertically,my toenails are teeny but my big toenails also have ridges but not splitting,so maybe it is down to the nail polish, take vit d + K2 every day, was on calcium from the Dr but stopped as I was scared it would build in all the wrong places,I had a bone density scan and have osteopenia,this was over two years ago now x
