Part 1 of 2
Almost everyone has experienced that “pins and needles” sensation in the hands or fingers after leaning on an arm for too long. In most cases, it’s harmless and disappears once circulation returns. But when tingling or numbness occurs often, it may signal an underlying medical condition that deserves attention.
Possible Causes of Hand Tingling
1. Neurological Conditions
-
Multiple Sclerosis (MS): MS damages the protective sheath around nerves, disrupting communication between the brain and body. One result can be reduced sensitivity or numbness in the hands.
2. Spine and Joint Disorders
-
Cervical Osteochondrosis: Wear and tear in the cervical spine can compromise blood flow and nerve conduction, leading to headaches, poor coordination, and tingling in the arms and hands.
