Most of the data you reported (Restless Leg Syndrome, numbness and tingling in arms and legs, severe earache for 3 months, sharp temple pains, daily chronic pain in the base of the head, clicking in the back of the neck) are related to subjective symptoms which can not be measured. You might want to visit a neurologist for EEG (Electroencephalography) and/or evoked potential test to determine if some damage in the brain or along the nerves has occurred. When you visit the doctor try to be calm, do not burst all your symptoms at once and do not oppose the doctor about the tests and the treatment at the very moment he suggests something. Thus, he/she might take you more seriously and you will avoid being taken as hypochondriac.
