Under Eye Filler and Severe Pressure on Forehead?

 

Sometimes you may experience pressure on the forehead. When injected under the eyes the forehead muscle becomes tense.

This is probably just a sinus infection and coincidentally had fillers applied to the tear troughs recently. Give it time and if you're still concerned, follow up with your medical provider

You have sinus pressure and headaches with radiological evidences of a sinus infection.  The pain and pressure you are having are secondary to your infection, and it would be extremely unlikely that the filler underneath your eyes would be a cause.
