Constant Heaviness in head for 2 yrs.

I have heaviness in head for the past 2 yrs. For the past few months, I’m having frequent migraine now a days with more during evening and morning. I’m active, healthy, and happy aside this happening. I have had every test, MRI, CT Scan of brain, all turning up normal. I have 24/7 head pressure, fog and pain. I get stabbing pain randomly in head. My ears feel full and I feel pressure behind eyes and ears. This is all worse when I wake up. Sometimes it’s not as strong as other time but it’s always there. Sometime there’s no pain and just the pressure. This makes me feel very nervous. I'm taking Etizolam 0.25 sometimes. Please help and advice, as I’m suffering a lot, including my professional and personal life.
