I read your question carefully and I understand your concern. Judging from that description of headache, concentrated in the eyebrows and increasing by direct pressure, I would say that the most likely cause would be sinusitis, inflammation of the sinuses. Often this occurs in the setting of an upper airway infection involving the nose, throat and ear so the fact there are hearing symptoms is compatible with it. So I would see your primary physician or an ENT specialist to confirm the diagnosis through direct exam and imaging, if confirmed treatment with decongestants and antibiotics may be needed. I hope you get better soon.
