When a patient has had an injury to a joint or limb, leg pain can develop from these pain syndromes. To treat the pain a series of injections are administered. To prepare for the treatment the patient will lay on his or her side while an IV line begins running a numbing anesthetic to the skin and tissue of the sympathetic nerves as well as a medication that will calm the patient. The physician will then use a fluoroscopic x-ray unit to inject Contrast dye to identify the areas affected and to determine the location of the injection. A mixture of anti-inflammatory medication is then injected to block pain signals from arriving to the brain. Legs may feel frail once the procedure is completed but the pain is only temporary. The block procedure should be repeated every week and until the pain is fully relieved.
