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.
Possible advantages:
* Less pain
* Lower risk of nerve damage or accidental intravenous injection
* Easier to perform?
Possible disadvantages:
* 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?

Yeah. I use this all the time. Onset is slower but the duration and effectiveness are great.

Just wanted to say that I tried this myself today (2ml of 2% lidocaine subdermally at the crease of the finger) and it worked flawlessly. I haven't tried other injection methods, but I can't imagine why anybody would choose them over this one for a fingertip procedure.

Haven't tried this yet, I'll have to give it a try.
