A brachial plexus block is a medical procedure that involves the administration of a dose of local anesthetic into an area either in your neck, above your collarbone or into your upper arm (near the armpit). This block may be performed as a single injection or a very small catheter may be inserted into one of these areas in order to provide continuous or repeated administration of medication. This treatment has brought relief to many patients who suffer from chronic pain in their arm and shoulder.
How quickly can I expect pain relief?
Relief is fairly quick (within 10 to 15 minutes) after the injection of medication.
