Why can't we shut off nerves causing pain with some sort of procedure that doesn't involve risky surgeries and cutting through arteries and tissue?
I feel like one way could be to implant a magnet or something on surrounding nerve area that draws in medicine from the blood supply. Or just an injection that permanently disables the nerve from transmitting. Why is this too hard?

Capillaries, osmosis, and magnets themselves don't work this way. The compound will be active elsewhere in the body still, and thus cause side effects.

This is already done with botox, ethanol, etc.
Gamma knife / rhizotomy lesions nerves and prevents them from firing. Though it comes at a cost.

Type 2 trigeminal neuralgia. Don't want increased probability of stroke, surgery bullshit, or loss of sensation outright without a guarantee of a permanent solution. I leave it be.
