Many people think that cervical spondylosis is just neck pain, but actually, after developing cervical spondylosis, there can be other symptoms. For example, the early symptoms of cervical spondylosis are generally diverse and complex. Most patients initially experience mild symptoms, which gradually worsen over time. Some patients have severe symptoms, and clinically, it is generally divided into five major types. The first type is cervical cervical spondylosis, where the main symptoms are soreness and swelling in the head, neck, shoulders, back, and arms, neck stiffness, and limited movement. The soreness in the neck and shoulders can radiate to the suboccipital area and upper limbs. The second type is vertebral artery type, where patients generally experience dizziness, a sensation that the room is spinning, and severe cases may include nausea, vomiting, and bedrest, with a few instances of vertigo and sudden collapse. The third, and most common, is spinal cervical spondylosis, where it is particularly strenuous to hold objects, which often fall to the ground, instability in walking, as well as spasms in the neck and shoulder muscles, increased muscle tone in the limbs, and even paralysis. The fourth type is radicular cervical spondylosis, with neck pain, acid swelling and distension pain in the unilateral or bilateral upper limbs, numbness, and sometimes intense pain that is unbearable. The fifth most common type is sympathetic nerve cervical spondylosis, where patients may experience blurred vision, dizziness, abnormal sweating, persistent low-grade fever, palpitations, chest tightness, rapid heartbeat, often with insomnia and frequent dreaming. The sixth type is the mixed type, which may present a combination of symptoms from the types mentioned above.
