PRP facial injection for neuropathic pain - effective and useful?

You are absolutely right — recent studies have shown that PRP (Platelet-Rich Plasma) contains several growth factors that may promote peripheral nerve regeneration and reduce neuropathic pain.
Among these, NGF (nerve growth factor) and BDNF (brain-derived neurotrophic factor) play a key role in supporting axonal repair and improving nerve conductivity.

In cases of trigeminal neuralgia or post-dental neuropathic pain, PRP injections near the affected nerve branch can potentially stimulate micro-regeneration, reduce inflammation, and improve local circulation.
However, outcomes depend heavily on injection technique, depth, and anatomical precision, as the trigeminal nerve lies close to critical facial structures.

When performed by a doctor trained in facial or nerve regenerative medicine, PRP can be a safe, complementary therapy — especially for patients who have responded well to it in other regions (like your knee).
It is not a guaranteed cure, but it may accelerate recovery and reduce chronic discomfort over time.
