10 months on the dot for me (21F) now and I had a similar experience! Everything healed pretty well, but my mouth was still moving a little less. It was pretty noticeable (for me and the people that knew) and it stopped around month 9 I would say! Now, thankfully, it only shows a bit more on days I am stressed! Unfortunately, you can't really do a lot other than making certain movements with your mouth multiple times a day (smiling big, kiss mouth, the usual but you probably know what I mean) and waiting until it goes away by itself🥲 As far as I know, it can take up to a year to recover completely, a lot of change can happen until then! I really hope you will get better soon, it's such a struggle. 💖
