Neurogenic cervical spondylosis is most commonly seen in the 4th-7th cervical vertebrae, so it is recommended that the ointment be applied to the 4th-7th cervical vertebrae. As the cervical vertebrae are deeper, it is difficult for the medication to reach the cervical vertebrae. And the ointment treatment is mainly for muscle strain at the back of the neck to relieve pain. Then nerve root type cervical spondylosis is mostly seen in the 4th-7th cervical vertebrae, and pain usually occurs here as well, so it is recommended that the ointment be applied to the 4th-7th cervical vertebrae. There are seven cervical vertebrae from the top down, and the seventh cervical vertebrae has a longer spinous process. It is because the spinous process of the seventh cervical vertebrae is longer, so it is better to locate it, and it is the seventh cervical vertebrae that protrudes the most when the head is lowered. The seventh cervical vertebra is the one that protrudes the most when the head is bowed. Therefore, the ointment can be applied to the seventh cervical vertebra when the head is bowed. If you want to know the exact location, we recommend that you consult a doctor, and please follow the doctor’s advice or read the instructions before use.
