Several years ago a colleague, also a tradie who ran a business employing 6-8 people had same thing, both hands - could hardly hold steering wheel.
Doc & surgeon recomm cut & rehab...not v happy with 6-8 weeks off.

Chinese employee suggested seeing his chinese & trad trained doc.
Gave him a repulsive brew to drink & acupuncture & massage....took several months to work but 16 years later, still hasn't had to go the cut.

Told another friend who was due to have both wrists done....
she went thru same process...fixed one wrist, but not the other.
if it works for you, then try a REPUTABLE alternative.
Explore the alternatives - objectively - & make an informed (multi-discipline) decision
