These symptoms may be caused by stress.

The nervous system is said to largely contribute to hot flushes.
Hot flushes occur when the autonomic nervous system becomes imbalanced due to stress, etc. making it hard for one to slow down. This in turn leads to a rise in blood pressure and metabolism and the active secretion of hormones.
Okuda Cranial Nerve Medicine helps to alleviate hot flushes by relaxing prolonged nerve tension.
People suffering from stiff shoulders or a pain as though their head is being squeezed tightly are believed to develop headaches and a heavy head sensation due to an imbalance of the sympathetic and parasympathetic nerves of the autonomic nervous system caused by stress, overwork and muscle stiffness.
Okuda Cranial Nerve Medicine dispels stress and emotional tension, thus alleviating headaches and heavy head sensations.
Stiff shoulders involves pain in the neck and shoulders caused by fatigued muscles in the neck and around the shoulders and poor blood circulation.
Contributing factors may be working at a desk for prolonged periods of time in the same position, tired eyes, or emotional factors such as tension and stress.
Okuda Cranial Nerve Medicine alleviates the stiffness in shoulders and neck caused by tension and stress.
Irritability occurs when things do not turn out the way we had hoped, trouble in human relationships, difficulties in the workplace and so forth.
Irritability can also occur due to emotional imbalance, stress, lack of sleep or a nutritional imbalance.
Okuda Cranial Nerve Medicine alleviates emotionally irritable states and helps a person back to their normal selves.
Anxiety is believed to derive from an imbalance in neurotransmitters in the brain, such as serotonin and dopamine.
People develop anxiety due to changes in their environment, worries, tension, fears, feeling frantic and so on.
Okuda Cranial Nerve Medicine helps to return people who have reached a state of emotional anxiety back to their normal selves.
In addition to ear or brain-related illnesses, stress may be a cause of dizziness. Stress causes an imbalance in the autonomic nervous system, which regulates the rhythm of the body, causing our actual lifestyle rhythm and body rhythm to become out of sync, thus leading to dizziness.
Okuda Cranial Nerve Medicine has the ability to relax nerves and help them back to a state close to normal, thus alleviating dizziness.
Ringing ears may be caused by aging or ear-related illnesses but the causes are yet to be clearly identified therefore the treatment is unknown.
Okuda Cranial Nerve Medicine helps to relax nerves fatigued from stress, etc. which can partially alleviate ringing ears.
