I had a silicone chin implant placed with under-chin incision 11 days ago. In the last 24/48 hours I'm VERY concerned. My swelling has drastically increased, the muscles under my chin (and even down my neck) are very sore, I struggle to smile/chew/open my mouth and even swallowing hurts the under-chin muscles. My PS is saying take acetaminophen and apply warm compress. Can someone please tell me if I should be concerned? Note that I had NO signs of double chin before, just receded chin.
