are you using high cbd strains or any old strain for the topical?There are different types of pain. topical may be the way. Have him put raw oil on his hand and rub it into.the affected area. That will tell you if it will relieve the pain topically. Arthritis, fibromyalgia, skin lesions etc.. all seem to be eased or completely relieved by a strong topical so it's worth a shot.
Unfortunately he may need nerve surgery In the hand if it persists.
Nerve pain is tough. I take a nerve modifying medication myself....
