Suggest Treatment For Cranial Hypertension

Hello Sir/Madame, I am a 21 years old male and I suffer from chronic ultrasound noise in my head or ears. Despite the absence of any acoustic source, and in a complete calmness, I hear a sort of ultrasound and sharp noise in my head, like if I suffer from a cranial hypertension or something. I wanna know please how I can be relieved from this, and is it caused by chronic stress and sleep disorder (my case) or does this cause chronic stress and sleep disorder (which is the cause and which is the effect) ? Thank you for giving advice and how I can cure this.
