Tinnitus (Ringing in the ears) I got a hack for that! Mix together 1 tablespoon of Diclofenac Gel and 1 tablespoon of lidocaine 4%. Rub it on and use a micro current on top of the applied solution. Do this for 5-7 minutes two times a day. Click the link in my bio for an Amazon shopping list! #fyp #tinnitus #ringingears #otchacks
