Subcutaneous Single Injection Digital Nerve Block
Most guides for performing a digital nerve block, including some created or referenced by biohackers, use a "traditional" approach. This involves injections through most of the thickness of the finger, on either side, in close proximity to nerves and blood vessels. However, a modern, less invasive type of nerve block can be performed with only a single injection just below the skin. Here's a short blog post outlining it. Studies here, here, and here provide some more in-depth info.
- Less pain
- Lower risk of nerve damage or accidental intravenous injection
- Easier to perform?
- Less reliable at numbing dorsal digital nerves, though this shouldn't be an issue with fingertip magnet placement.
- Unknown possible complications of accidentally penetrating tendon sheath or tendon
Has anyone tried this technique? Any thoughts about it?
