My 97 y/o father-in-law has grit in his ears on a daily basis. Has been going on for about 9 months. It started after he was put on iron for low hemoglobin, and his provider thought it might be his body's way of getting rid of excess iron. However, he's been off the iron now for about 4 months and still having grit in his ears. He says it varies in color, white and darker. Could this just be normal ear wax for him now or should he see an ENT doctor? Oh, yes, he says it's also in his navel.
