Tinnitus and Hyperacusis. Side effects?

I have mild ringing in left ear from 9 months and sound sensitivity from certain sounds (sounds from TV, mobile, speakers etc even at moderate volume). I have tried Gingko Biloba and Neurobian in the past (3 months back) but did not see any improvement. So, I use foam/silicon ear plugs to protect my hearing from loud noises and from sounds from TV, speakers. I am doing overall okay though my quality of life is restricted. Recently I visited a doctor and he prescribed Tinnicar (Caroverine 20mg) for 1 month and Ginkoba M. I am not sure if Tinnicar can help and I want to know if it can cause any side effects? Basically I don't want to over Medicare myself since I have accepted this issue. Any guidance will be very helpful. Attached my Hearing test and impendence test results. Thanks.
