Researchers have developed a local anesthetic that can numb tissue for weeks rather than the few hours achieved by current drugs such as lidocaine. The advance could transform pain management after surgery, dental procedures and chronic pain treatment, reducing the need for repeated injections or opioid painkillers. Reports describe the work as a significant step in pain control, though wider availability will depend on further testing and regulatory approval.
