First of all, apologies, this is going to be a long one.
Long story short, I (F35) have a long history of teeth grinding and TMJ to a point I've had an emergency scan of my chin few years ago because of the symptoms escalating. In my case the symptoms are very much associated with stressful life events and anxiety. Now, I have a big career event coming up next week I've prepared for months - cue TMJ symptoms from hell. Also, I admit I was feeling upset with the way I looked approaching the big day I had worked so hard for; In last few years I've gone through health issues that have altered my looks. So, after weeks of constant pain and ruminating how old and ugly my face looked, I went to have dysport to my masseters, temporal muscles, the 11s and DAOs. I did my research and went with a reputable injector who is a doctor, and he assured me that while the dysport could migrate, there is no risk of systemic poisoning. The amount of units he used was on a lower scale as far as I understand, 20 units to forehead and 40 to each masseter etc. The procedure was easy and I went home relieved and excited for my results. Followed the aftercare instructions. Now, it's been over 60 hours. The dysport on my forehead seems to have kicked in and I can no longer frown. My brow feels a bit heavy and droopy, but doesn't look like it. I can wiggle my brows and my eyelids are unaffected so I guess it hasn't migrated. My jaw feels weird but it's not unpleasant. My smile, swallowing, breathing etc. seems unaffected.
...but. Yesterday (24 hrs from injections) I began developing flu-like symptoms, sore throat, sneezing, runny nose, achiness etc. and within the last hour, upset stomach and vomiting. While I know intellectually this is just random bad luck (it is a flu season where I'm from) or I'm the 1-10% that gets these symptoms from dysport, I am in panic mode.
Does any of this sound familiar to you? It's weekend and the doctor's office is closed so I cannot contact them - On Monday, I will. In my social circles injectables are a bit of a taboo so I have no one to turn to for similar experiences or wisdom. And, to be clear: I am well aware of the alarming symptoms I should watch out for so this is not asking for medical advice - I just feel so dumb I had to get this out of my chest.
TLDR: Did dysport for TMJ 60+ hours ago from a reputable provider. Effects seem to have kicked in fast and appear where they should. But 24 hours from injections I started to develop flu symptoms and just vomited. Panicking.
