I had matricectomy done on both my big toes when I was 16 and I am so happy that I did!
I used to constantly get ingrown toenails, but I haven't had one since. I used to constantly have to worry about cutting my nails properly etc., but now I'm worry free. My nails look fine, and no more painful ingrown nails. The doctor said I had one of the widest nail beds he had ever seen.
