CNH is not exactly a critical condition and in most cases, it does go away on its own, after persisting for several months. All you need to do is ensure that it doesn’t get irritated by maintaining certain self-care techniques.
First off, you need to sleep on the side that doesn’t contain the CNH nodule, so that no pressure is exerted on the sensitive skin. Applying petroleum jelly to the irritated nodule can also help relieve the irritation caused by the nodule. In some cases however the nodule catches infection and the CNH becomes critical. At this point, your doctor might suggest antibiotics or a surgery to eliminate the nodule.
