Find the cause?: Good morning, nagel itchy rash with red bumps suggests that your immune system is trying to reject something such as an allergen or a virus. The itching is a signal that something is not right. Your doctor will try to find the cause for the problem by doing some tests and then try to cure it permanently. If it is due to an allergen, practice avoidance. However, finding the cause is the first step.
