Arm Intervention/treatment
Experimental: Transdermal Lidocaine
All patients will be in this arm. This arm will be the transdermal lidocaine group.
Drug: Transdermal Lidocaine
The intervention will use 5% commercially available transdermal lidocaine in clinical practice for the treatment of tinnitus. This dose will be tailored to patient preference.
Other Name: 5% Commercially Available Transdermal Lidocaine

Primary Outcome Measures :
  1. Tinnitus Functional Index (TFI) change at 4 week intervals up to a maximum time frame of 12 weeks [ Time Frame: At time of enrollment and every 4 weeks thereafter up to a maximum time frame of 12 weeks from date of enrollment. ]
    The primary study endpoint is change in tinnitus tolerance based on the tinnitus functional index. TFI will be measured at initial appointment and will be measured again at 4±1 weeks for any change in outcome, then again at 8±1 weeks for any subsequent change to outcome, and finally at 12±1 weeks follow-up for any subsequent change to outcome, up to a maximum time frame of 12 weeks from date of enrollment.
