May need to use the "Detox Methotrexate" program to help clear the chemo chemicals.
It may also be necessary to heal nerves damaged by the chemo...
"Stimulate Repair Nerve Damage" may help with this.
Other general ear programs may help, but above all - it is important to remember that the tinnitus is a chemical induced damage, so the first need is to get rid of the chemical, then repair the damage... Who knows how much chemical remains and how extensive the damage, so PATIENCE is the order of the day to allow the body to clean itself and heal. It probably won't fix it all quickly.
