Is it normal to experience twitching in upper lid few weeks after tear trough filler?

In my capacity as a GP I can day that upper eyelid twitching is quite common and it is not related your recent dermal filler. An eyelid twitch is more of an annoyance but if it persists more than a few weeks make sure you pop in to see your GP for them to examine you. Eyelid twitching often settles on its own. Hope that reassures you 🙂
