Hand numbness accompanied by a crawling sensation, also known as "formication," is a common neurological symptom that may be caused by various factors. The following are possible causes:
1. Nerve compression: Carpal tunnel syndrome, caused by compression of the median nerve at the wrist, is commonly seen in individuals who repetitively use their hands for prolonged periods.
2. Nerve damage: Conditions such as diabetes and thyroid dysfunction can cause peripheral neuropathy, leading to hand numbness and crawling sensations.
3. Circulatory problems: Long-term poor posture or impaired blood circulation, such as Raynaud's phenomenon, may also cause abnormal sensations in the hands.
4. Medication side effects: Particularly chemotherapy drugs, which can cause neurotoxicity leading to numbness in the hands and feet.
Management recommendations:
1. Address the underlying cause: If caused by chronic conditions such as diabetes or hypertension, it is important to control the related parameters.
2. Nerve nutrition: Neurotrophic medications such as vitamin B1, B6, B12, and methylcobalamin can be used.
3. Physical therapy: Treatments such as acupuncture and infrared therapy may help alleviate symptoms.
4. Anti-allergy treatment: If diagnosed as allergy-induced, anti-allergy medications should be administered.
