Understanding Pins and Needles: What's Really Going On?

The video explains the sensation known as pins and needles, medically termed paresthesia. It describes the causes, focusing on transient paresthesia due to pressure on nerves, particularly the sciatic nerve. The anatomy of the sciatic nerve and its branches is detailed, explaining how pressure can lead to a temporary shutdown of nerve signals, resulting in numbness. The video also covers the recovery process, where the nerve 'reboots,' causing a rush of signals interpreted as pain or tingling. The potential for long-term damage in certain scenarios is also discussed.
