Misconceptions: Cervical spondylosis is basically understood by everyone, however too much knowledge also leads to some misconceptions as well. For example, hand numbness is always thought to be cervical spondylosis, go for an MRI and find a slightly bulging cervical disc, so they start a series of cervical spondylosis treatment. However, under normal circumstances when people get older, cervical spondylosis is more or less mild or severe, but another important disease that causes hand numbness is ignored by everyone, so that many people miss the best time for surgery, and this disease is carpal tunnel syndrome. Symptoms (impact on life): carpal tunnel syndrome is a peripheral nerve jammed in the wrist caused by numbness in the fingers, numbness and pain symptoms, severe cases will appear atrophy of the greater interphalangeal muscle, affecting hand function. The incidence of the disease is high, especially in middle-aged housewives more common. Treatment principles: Early carpal tunnel syndrome can be considered conservative treatment, oral non-steroidal anti-inflammatory drugs and neurotrophic drugs can relieve the symptoms, but cannot relieve the cause of the disease. As the disease progresses, atrophy of the interosseous muscle of the hand can occur, at which point surgery is unavoidable, and the sooner it is done, the better the recovery of hand function.
