👉 Embolemia is a medical condition that occurs when the muscle around the brain, called the brainstem, contracts too much. This can cause pain and discomfort in the head and neck area. It's usually caused by damage to the nerves or blood vessels that supply these muscles. Symptoms may include numbness, tingling, and weakness in the arms, legs, and face. If left untreated, embolemia can lead to permanent brain damage if not treated promptly.
