It may be accompanied by tinnitus, a sense of ear congestion, vertigo and other Symptoms.Stellate ganglion block increases the blood flow and blood velocity in the inner ear, keeping the body's vegetative, endocrine and immune functions normal.The branches of the facial and linguopharyngeal nerves are connected to the inner ear, and local injection can nourish the nerves and improve local circulation.
