I have mild pressure/tightness on forehead & face all the time, for 8 years. i feel better only when i bow my head looking on floor. what could it be?

Forehead pressure: What happens when you lie down or sleep? Could be sinusitis, allergies, reflux, try prevecid, keep food diary as when it worsens -diary, gluten soy may be culprits. Could be-trigeminal/cervical/TMJ (press bone by ear)irritation , or rarely may be heart ASD or aortic stenosis have murmurs that improve with decreased flow ( just areas to check-do not decrease flow) Would get echocardiogram, f/u w/d
