OK now dont let this over stress you . but it means that the toenail is dead in that area, and there is maybe a fungus that has caused this or blood flow problems , and ill ask you a question also. do you have blood sugar problems? this may be the cause also. but this needs to be seen to right now, before it really gets out of hand and this is starting to spread and will rot off the whole toenail, and maybe the toes if something is not done, and this really causes problems for the person, you need a good podiatrice and soon , and please do this before it really affects you feet!
