Last December, my toddler tried to take his older brother's temp with a thermometer. Only it wasn't an ear thermometer. Popped his eardrum. It did gradually heal up. If I look in his ear, the eardrum is shiny and not red. BUT there is still a large black scab over nearly half of the eardrum and extending a bit into the ear canal. Tried peroxide to see if it was just a wax clump now, but it really does seem to be a scab. He complains that it feels like something is poking his eardrum. The pediatrician said he wasn't really sure what could be done...Any suggestions?
