Yes. After evaluation by a physician, if surgery is not suitable or the pain severely affects daily life, nerve block is a safe alternative treatment.

General painkiller injection (systemic):The medication circulates throughout the body via the bloodstream, like a “widespray.” While it can relieve pain, its effect is short-lived (only a few hours) and it easily causes side effects such as dizziness, drowsiness, or gastrointestinal discomfort. Nerve block (regional):Through precise ultrasound guidance, the medication is injected directly next to the “pain-causing nerve.” Like a “precision sniper,” it is highly targeted and has a stable and long-lasting effect (usually lasting several weeks to months), effectively reducing dependence on oral medications.

It is recommended to use it no more than 4 times a year to avoid the cumulative side effects of steroids.

The numbness usually recovers within hours and does not have a long-term impact on walking or muscle strength.

It can generally last for 2 to 4 months, but this may vary slightly depending on individual constitution and nerve response.

The knee joint has many nerves, so injections may be needed at 4-5 sites; the hip joint requires about 1-2 sites. Most patients only require local anesthesia. General anesthesia is only necessary for those who are extremely nervous or unable to cooperate.
