How is pain treatment guided?
The treatment of pain is guided by the history of the pain, its intensity, duration, aggravating and relieving conditions, and structures involved in causing the pain. In order for a structure to cause pain, it must have a nerve supply, be susceptible to injury, and stimulation of the structure should cause pain. The concept behind most interventional procedures for treating pain is that there is a specific structure in the body with nerves of sensation that is generating the pain. Pain management has a role in identifying the precise source of the problem and isolating the optimal treatment.
Fluoroscopy is an X-ray guided viewing method. Fluoroscopy is often used to assist the doctor in precisely locating the injection so that the medication reaches the appropriate spot and only the appropriate spot. Ultrasound is also used to identify structures and guide injections.
