Chronic pain is the most common cause of long-term disability. It lasts longer than "normal healing" (several months), and can cause severe problems.
Anesthesia (Conscious Sedation)
Conscious sedation is a type of anesthesia that makes the patient feel very relaxed. It reduces painful sensations and the awareness of pain. It is not intended to put the patient to sleep, and will wear off quickly after a procedure. Conscious sedation is commonly used for simple procedures that can be completed quickly.
