Hi everyone. I'm new here. My vet's office is closed and I'm really worried. My 1 y/o german shepherd. 4 weeks ago she had a benign cyst removed from the top of her head so she has been wearing the e collar. Just today she started flapping her ears and they feel a little swollen. She isn't standing her ears up either. I was reading about hematomas but they do not feel fluid filled or maybe not yet. I am so worried about her. I'm worried that maybe she's hurt her ears from knocking them against her e collar. Does anyone have any ideas as to what this could be? I'm taking her to the vet tomorrow morning as soon as they open. Thanks everyone.
