The phenomenon of tingling pain in the left back of the head is very common in clinical practice, and the decision can be made only after perfecting the corresponding examination. However, some of them also need to be judged accordingly based on physical examination, such as sometimes incorrect sleeping posture, maintaining a posture for a long time, compressing the large occipital nerve and causing pain in the large occipital nerve, which may also cause the phenomenon of tingling pain in the left back of the head. If the patient sleeps poorly, often stays up late, and looks at the computer or cell phone for a long time, it may also cause neurasthenia and insomnia, which cause headache, and sometimes cervical spondylosis may also involve the tingling pain in the left back of the head. However, if accompanied by symptoms of nausea and vomiting, it may be a case of cerebral hemorrhage, which needs to be examined accordingly and diagnosed clearly.
