Is it normal for some bleeding to continue even after 7 days of tympanoplasty+mastoidectomy? My father had it done 7 days ago and even now some blood continues to leak out from the cotton stuffed in his ear canal. He's very active and can't sit still without doing something, so he keeps bending down and lifting something (not more than 1kg) every now and then. I hope it's not causing the bleeding right?
