I have read some of your posts on this topic, in my case, I have an extra build up of skin thats attached to my nail which eliminated the free edge of my nail. My doctor said this was called pteringum inversum unguis, (im not sure if i spelled that correctly), but that it what he said I have. I was just wondering how common this is, and if there are any treatments for it. To give a good example of what it looks like, check out this link. Pterygium Inversum I would like ot point out however that mine is not as bad as this, but it still looks similar.
