Does trigger thumb surgery hurt? Do they cut the whole joint open?

Nothing serious. Minor surgery, under local anesthetisia , they do not cut the whole joint open. Thank you.
Very little.No. Trigger thumb is tightening and inflammation of the the tendon sheath(the fascia which surrounds the tendon).The operation is release of the tight tendon sheath, which is mostly done under local anestheasia or monitired anesthesia as an outpatient procedure.So, the joint is not violated at all.
Minor surgery. This is relatively minor surgery that does not involve the joint as long as it is not an advanced or comicated case. It involves releasing a band like constriction with near immediate release but please follow postop instructions and therapy and all should proceed well.
