About a week ago I found myself stuck wearing shoes that were too small for me and couldn’t get home for a few hours. As a result of this I’ve developed a bruise on my big toenail. It covers more than half of the toenail and is mainly light blue but goes very purple at the base. Dr Google says some worrying things and that I should take myself straight to the doctor, and although I am getting a little worried I do think they will laugh. It seems to be getting worse, though and the bruise is deepening in colour. Is it anything to worry about?
