Cisplatin is known to cause problems with hearing in some patients. When John had his chemo, he was first sent to Toronto General for a hearing test, which I think was the baseline. Then a year after treatment he had another hearing test and there was significant loss. Please monitor the ringing in your ears. As well, let the team know if you feel any tingling in your finger tips. That may be a sign of neuropathy. John did not get his third bag of Cisplatin because he had developed deep vein thrombosis at that point and he was in very poor shape. All my very best.
