There are a couple of rather serious reasons why the scab on your nose will not heal, and the first one could be that you are suffering from diabetes. This disease means that the wound will either heal slowly or not at all. The problem may even be cancer. Skin cancer is actually more common than you think and generally occurs on the face and the ears due to the exposure of your face and ears to sunlight and UV rays.
You may be lucky, however. The problem could be that you are subconsciously picking at the scab. This would keep the scab from healing, meaning that you aren't suffering from either of the problems I have already outlined. If this has been continuing for quite a while then you should really see your doctor. Looking on the Internet can give you a general clue of what is going wrong but ultimately it cannot diagnose you and it will not help you cure the problem. The only person who will be able to properly diagnose you with whatever condition you may have is your doctor, and so you should make an appointment to see him or her as soon as possible.
If they have any suspicion that you have diabetes, they may ask you some questions about your diet and whether there have been any changes recently. They may also consider your BMI as sometimes diabetes can be a result of poor health and a bad diet. If it's cancer they may have some blood tests, amongst other tests, to see what is happening to the skin. What you can be sure of, however, is that if you are diagnosed with either of these problems then your doctor is the best person to help you. He or she will direct you to the best people to provide you with surgery if necessary, and they will provide you with all the support and medication that are required to keep you healthy.
