Cervical spondylosis is a patent for people after 40 years old, but now patients with cervical spondylosis between 20 and 30 years old abound, and even primary school students have cervical spondylosis! The reason is simple: sitting at a desk for a long time is very stressful and I don't know how to recuperate, so cervical spondylosis came early.
I suggest your mother check it quickly and find the high cervical vertebra of this pot.
