Features 1. Innovatively alleviate migraine and headache symptoms: Ear pressure devices activate multiple brain nerves in the ear canal through photopneumatic pressure stimulation. Through scientifically calibrated pressure modulation within the device, ear pressure sensors can promote precise stimulation in the ear canal, thereby sending signals to the corresponding brain nerves in the brainstem, which is related to almost instantaneous balance and pain relief. 2. Immediate and long-term relief experience: The development purpose of this ear pressure device is to naturally and immediately alleviate the tension, pressure, and pulsation of patients, even those with the world's most severe and complex symptoms of cluster headaches, tension headaches, and migraines. 3. Ear pressure relievers: Ear pressure relievers can alleviate tension and relieve headaches. Pressure is generated by activating the eardrum and brain nerves in the ear canal through light and pressure stimulation. 4. The world's first consumer migraine product that naturally relieves headaches and tension caused by migraine symptoms through inner ear pressure stimulation.
