Is it insulinoma??

Do you know by chance...is it a side effect for thhem t o get excessive wax build up in their ears and maybe yellowish discharge from using prednisolone? Hopes ears have been awful since being on these meds and I have to clean them all the time and now her eyes are also getting a bit pink rimmed and when I clean them with a damp cloth there's like a yellow discharge there and it's kinda the same with her ears
