About 2 weeks after receiving Botox injections in my chin I noticed when scrubbing my face that my chin would involuntarily seize up and almost curl upward get larger and swell and contract and pull down the sides of my mouth and turn red. While this still happens when my chin is touched, at 4 week I was no longer able to swallow solid food. My throat either won’t finish the swallow and I have to cough it up or food particularly get stuck. Has anyone ever heard of this happening?
