Genicular Nerve Block. This outpatient procedure is an injection of anesthetic to the genicular nerves. These are the sensory nerves that transmit pain signals from the knee to the brain. Anesthetizing these nerves can disrupt the pain signals caused by degeneration of the knee. A genicular nerve block can provide temporary pain relief.
The trigeminal nerve is a paired cranial nerve that has three major branches: the ophthalmic nerve (V 1), the maxillary nerve (V 2), and the mandibular nerve (V 3). One, two, or all three branches of the nerve may be affected. Trigeminal neuralgia most commonly involves the middle branch (the maxillary nerve or V 2) and lower branch (mandibular nerve or V 3) of the trigeminal nerve. An individual attack usually lasts from a few seconds to several minutes or hours, but these can repeat for hours with very short intervals between attacks.
