Hi, I Was Looking Into Adverse Reactions To The Combination

Hi, I was looking into adverse reactions to the combination of ipiluminab and nivoluminab 2 years after treatment . My husband is getting hard of hearing and he just got out of the hospital after going through many tests, eg CAT scans of back& chest, brain MRI, chest x-ray ultrasound of his gallbladder. The only test that came back abnormal was the gallbladder. the MD said it showed dilated biliary ducts and small gallstone which they do not believe to be the cause of the pain he has in his side/back. What do you think?
