Sinus Presure Behind The Ears & Head I Have Been Having Presure Behind My Eye Should I Be Worried?

I have been having presure behind my eye should I be worried? - sinus presure behind the ears & head

I had migraines a month ago for the first time in three days now I have pressure behind my eyes and mild headaches. When I had my headaches and an MRI was normal, this could only have allergies or sinus headache?
