Sometimes, hand numbness is connected to broader health concerns, particularly those that affect nerve health or blood circulation. Examples include:
- Diabetes: A common cause of nerve damage, especially in the extremities (diabetic neuropathy).
- Migraines: Some people experience tingling or numbness as part of a migraine aura.
- Multiple Sclerosis (MS): A disease of the central nervous system where numbness is a frequent early symptom.
- Stroke: Sudden numbness, especially on one side, can indicate a stroke and needs emergency care.
- Viral infections like shingles or herpes, which can affect nerve pathways.
- Raynaud’s phenomenon: A condition where blood vessels constrict, especially in fingers and toes, causing numbness and coldness.
- Hypothyroidism: An underactive thyroid can sometimes cause swelling that presses on nerves.
