Tinnitus isn”t an actual condition, but a symptom of an underlying problem, such as injury to the ear, a circulatory-system disorder or simple age-related hearing loss. Less common conditions are Meniere”s disease and acoustic neuromas. Some antibiotics, cancer medications, diuretics and almost 200 other medications are linked to tinnitus. The most common type of tinnitus is known as subjective, caused by problems in the outer, middle or inner ear where tiny hairs move as a result of sound-wave pressure. Tinnitus results when the hairs become bent or broken. It may be present constantly, some of the time or in one or both ears. http://www.alexiifi.com/synapse-xt-supplement-reviews/
