My neuroma was called a "sticky neuroma", was 3cm , and stuck to the 7th and 8th cranial nerve. My lip droops,and the nerve damage affected my smile,my eye closure, winking, puckering...The Botox helps with the pain and disfigurement.My neck muscles pull downward and are stronger than my facial muscles. Therefore, my neck muscles win! It is painful when they pull your face downward ! I also have twitching in my eye and cannot completely close it. The Botox relaxes the eye as well. Previously, I received several injections in my neck and around my eye and that worked well for about 12 years.I go about every 3 months for injections.For about the past year I am doing better without as much botox around my eye as far as closing it. My diagnosis has been Myokymia, Synkensis, and Lagophthalmos. BCBS covered it. Medicare doesn't cover Botox except for certain diagnosis. There is a diagnosis similar to mine that it does cover called Hemifacial spasms.I am now waiting on UTSW to help me with an appeal.Medicare covers only a portion of the bill and hasn't paid for the actual Botox itself which is $750!
