Straightening of the physiological curvature of the cervical vertebrae may cause headache and dizziness, soreness in the back of the shoulders and arms, weakness of the upper limbs, numbness of the fingers, stiffness of the neck, tightness in the chest, nausea, and panic. 1. Headache, dizziness: the normal cervical spine is slightly convex, the physiological curvature of the cervical spine, which is important to the human body. The transverse foramen of the cervical spine contains vertebral arteries. Veins and vertebral veins. If the physiological curvature of the cervical spine is straightened, to a certain extent, it will cause compression of blood vessels, resulting in insufficient blood supply to the brain, headache, dizziness and other symptoms. 2. arm pain, upper limb weakness, numbness of the fingers: cervical vertebrae straighten, but also on the intervertebral disc caused by extrusion, resulting in cervical disc herniation. The herniated disc will compress the nerve roots in the neck, which will lead to arm pain, upper limb weakness, numbness of fingers and other symptoms. 3. Shoulder and back pain: Due to the change in the physiological curvature of the cervical spine, the muscles and ligaments in the neck are affected by the imbalance and disorders, which leads to shoulder and back pain. 4. Neck stiffness: the anterior edge of vertebrae wear and tear each other due to the change of physiological curvature of the cervical vertebrae, and hyperplasia may lead to the symptoms of neck stiffness. 5. Nausea, chest tightness, panic: Straightening of the cervical vertebral curvature may also stimulate sympathetic neuropathy in the neck, causing nausea, chest tightness, and panic. The above symptoms cannot be directly diagnosed as cervical spine curvature straightening, you need to go to the regular hospital in time. Follow the doctor’s instructions to standardize the treatment.
