I have tinnitus. I ran across this item from HealthCentral.com.May l9, 2000. Lidocaine helps relieve ringing in the ears. it is injected into the ears 3 concesecutive days resulting in partial or complete relief on tinnitus in 70% of patients. This was reported at an American Otological Society meeting in Orlando, Florida. Can't seem to get any information on this.Drs. were John J Shea and Xianxi Ge of the Shea Ear Clinic in Memphis Tennessee. Does anyone know anything about this??
