Limb numbness

Introduction Frequent numbness on the far side of the limb is a symptom of neuroma. Neuroma usually refers to schwannomas from nerve sheath tissue, most of which are located in the limbs, armpits, and also on the clavicle, neck and other parts. It is a benign tumor with slow growth and generally no recurrence after resection. Located in the limb mass, it is fusiform, and its nerves often have numbness, pain, and hyperesthesia on the far side of the dominant limb. Compression of the tumor can also cause numbness.

The diagnosis of the disease is based on symptoms and signs. For example, a fusiform solid tumor is found on the limb, and there is a distal numbness of the limb, pain, hyperesthesia, and numbness in the oppressed tumor. The disease is first considered.

When the examination showed that the tumor was pink or grayish white, the base was not easy to move or pedicled, and the quality was hard. It was confirmed by pathological examination. In addition, peripheral nerve lesions and cervical spondylosis should be excluded. If it is a neurological problem, an electromyogram examination is needed to further confirm the extent and nature of the nerve damage. If the numbness of the hands and feet caused by other reasons, then go to other related departments for treatment.

Differential diagnosis

Limb pain: refers to localized pain in some part of an individual limb, mostly caused by local disease; it can also be induced pain or radiation pain in the proximal part of the disease, or early symptoms of systemic disease.

The transmission of various sensations in the limbs of healthy people depends on the unimpeded access of the brain to the limbs.
