Pressure pain in eyes and face after cheek filler 5 days ago.

I've recently had filler 5 days a go in my cheeks, the left side was fine, the right side was painful, bled an d swelled straight away. When I got home I had an extreme pressure of pain behind my eyes. After a few days of discomfort I have had it dissolved, I still have a twitching painful eye with floaters and pressure headache on that side. I've had medical advice , they just think it's a flare up and it'll all calm down. But I'm still concerned....
