Brief Answer:
Needs work up and management, focus on screeching

Detailed Answer:
Hello there and thank you for asking at HCM!

I read your question and i understand your concern. I believe the screeching sound of ear also called tinnitus is connected with headaches and triggering it. If one fixed might help the other.

So lets start with this screeching sounds in ear or in other words tinnitus. There isa long list for tinnitus to occur.

Blockages of the ear due to a buildup of wax, an ear infection, or rarely, a benign tumor of the nerve that allows us to hear (auditory nerve)
Certain drugs -- most notably aspirin, several types of antibiotics, anti-inflammatories, sedatives, and antidepressants, as well as quinine medications; tinnitus is cited as a potential side effect for about 200 prescription and nonprescription drugs.
The natural aging process, which can cause deterioration of the cochlea or other parts of the ear
Meniere's disease, which affects the inner part of the ear
Otosclerosis, a disease that results in stiffening of the small bones in the middle ear
Other medical conditions such as high blood pressure, cardiovascular disease, circulatory problems, anemia, allergies, an underactive thyroid gland, and diabetes
Neck or jaw problems, such as temporomandibular joint (TMJ) syndrome
Injuries to the head and neck
Drinking alcohol, smoke cigarettes, drink caffeinated beverages, or eat certain foods. For reasons not yet entirely clear to researchers, stress and fatigue seem to worsen tinnitus.

To know for sure what is causing it and remedy it accordingly, you need to visit an otorhinolaryngology clinic and they will sort it out after a thorough assessment and some work up if need be.

Headaches are the collateral damage. Take some acetaminophen meanwhile for the headache. That should resolve once the underlying entity is fixed.

I hope it helps. Take good cre of yourself and dont forget to close the discusion please.

May the odds be ever in your favour.

Regards
Khan
