Symptoms of peripheral neuropathy mainly include sensory dysfunction, motor dysfunction, and autonomic dysfunction.
1. Sensory dysfunction: Damage to the sensory branches of peripheral nerves may be manifested as decreased sensation or sensory hypersensitivity. Specific clinical symptoms include decreased sensation of pins and needles, decreased sensation of temperature, and decreased sensation of joint position and vibration to varying degrees.
2. Motor dysfunction: Motor dysfunction is mainly characterized by muscle weakness and inability to perform relevant movements. In the long run, muscle atrophy may occur, and the examination may find that the muscle tone is reduced and the tendon reflex is weakened or even disappeared.
3. Autonomic nerve dysfunction: damage to the autonomic nerves may lead to abnormal sweating, upright hypotension, etc. Damage to the peripheral nerves in the lower part of the body may also lead to impotence and impaired urination and defecation.
When symptoms of peripheral nerve damage appear, it is recommended to seek medical treatment in time.
