I was thinking that maybe the nail is just growing thicker due to the medication and appears to be a ridge at the point it begins. I would imagine it's the Evista (if it strengthens bones, it might do other strange things). I was thinking of calling the drug company to report this, but I should get some blood work done first to make sure nothing else is going on. I've also increased my calcium, although not but all that much. Well, I can't get my nails done right now, I'd scare the tech!
Thanks for your input.
