Low-level laser therapy alleviates neuropathic pain and promotes function recovery in rats with chronic constriction injury-possible involvements in hypoxia-inducible factor 1α (HIF-1α).

LLL - Low level laser therapy directly to the nerve's lesion has good result.

In conclusion, a low-level laser could modulate HIF-1α activity. Moreover, it may also be used as a novel and clinically applicable therapeutic approach for the improvement of tissue hypoxia/ischemia and inflammation in nerve entrapment neuropathy, as well as for the promotion of nerve regeneration. These findings might lead to a sufficient morphological and functional recovery of the peripheral nerve. J. Comp. Neurol., 2012. © 2012 Wiley Periodicals, Inc.

Anyone have tried like in the study ?

Apparently, the location is the key.
