What disease is the pain caused by pressing the lower left part of the back of the head

The pain of pressing the lower left part of the back of the head needs to consider the following diseases: 1. Occipital neuralgia, which is the most common. The tenderness point of the occipital nerve is just below the back of the head. If it is left, it is left occipital neuralgia. The pain is mainly limited to the part where the occipital nerve is distributed. There can be a palm-sized place. There may be tenderness in the tenderness point of the occipital nerve and its distribution area. The nature of the pain can be tingling, throbbing pain, swelling pain or burning pain. 2. Mastoiditis, a disease belonging to the department of five senses, is very similar to the tenderness point of the occipital nerve. If there is inflammation below the mastoid, it will also show tenderness, but it needs to be confirmed by CT examination of the head or thin CT examination of the mastoid. 3. Myofascitis, the patient's tenderness site will not be very limited, it may exceed the area where the occipital nerve is distributed and can involve the neck muscles downward. The patient is often accompanied by cervical spondylosis, and has a history of working with a long bow or sitting position.
