Episode notes
How Pressure Causes Paresthesia
- Pins and needles (paresthesia) happen when pressure on nerves and vessels reduces blood and oxygen flow.
- The nerves then send abnormal signals that the brain interprets as tingling and numbness.
Relieve It By Removing Pressure
- Remove the pressure on the affected limb to restore blood flow and relieve the sensation.
- The pins and needles usually go away quickly once normal circulation returns.
When Tingling Signals Disease
- Persistent or recurrent pins and needles can indicate nerve injury or underlying disease.
- Conditions like diabetic neuropathy or multiple sclerosis can cause longer-lasting or widespread paresthesia.
