The ENT I have been seeing suggested I start taking them for a few months. He said that about 50% of his patents see some type of improvement. I am always worried about new medications with the possibility of side effects and such so I haven't started them yet because I was starting some other new medications at the time, but plan to this or next week. I also saw an otoneurologist about my Tinnitus who agreed with my ENTs suggestion to go ahead and try them. He also issued some Thyroid and Audiology Tests. I would recommend seeing a otoneurologist as the appointment was very helpful is possibly leads on what could be causing my T. I am low on B12 as some blood results showed, so the otoneurologist thought that B complex vitamins would be good idea anyways. Since a deficiency in B vitamins specifically B12 can cause Tinnitus. I got my Tinnitus after a bad ear infection with lots of fluid build up, so the doctors I have seen so far are not sure if it is going to be permanent or not. Hope this info helps, I'll be sure to update when I start taking the Lipoflavonoids.
