Sinuses or trigeminal neuralgia?

Female 47 on pantoprozole 120 lbs .I started in January with a cold with a high fever and congestion by February I was super dry in my nose and sinuses And this awful pain down the side of my nose and in one nosril and under eye pressure all on one side of the face.ive took antibiotics steroids nothing changed .ENT then told me to remove a molar top tooth i did that no change.now he has given gabapentin for nerves in the face I have a deviated septum and mild enlarged turbinate and he said no reason for my pain but I'm dry to point of nasal gel everyday and now I have some postnasl and some mild congestion Idk if that is from the tooth removal or what .do this sound like nerve related issues in my face ? I'm so afraid to take gabapentin if it's not it .
