A stabbing pain in the back of the head in the right ear is usually caused by localized nerve pain. If the pain is caused by inflammation, it is usually a persistent dull pain. If the pain is neuralgia, it is usually a spike-like paroxysmal pain. In this case, there is an organic disease, such as trigeminal neuralgia, which is considered to be related to irregular work and rest, excessive mental stress, tension and strain. If it is caused by the latter, pay attention to rest, adjust sleep, you can use nerve-nourishing drugs to assist treatment, the symptoms can be improved. If it is caused by trigeminal neuralgia, you can use targeted pain medication. For some patients who are more serious and have poor results, trigeminal nerve blocking surgery can be chosen at a later stage.
