I'm so sorry you are having headaches with dizziness. Have you seen headache specialist or Ear/nose throat specialist as of yet?

I used to have chonic daily headaches. Early in life, my migraines were cyclic with "female" cycles, becoming daily in my 20's . After many years of not being treated sufficiently, I refered myself to an endocrinologist and was diagnosed with Hashimotos Autoimmune thyroid disease and hypothyroidism. Starting treatment with levothyroxine helped to reduce the severity and frequency of headache pain. Years later with increasing migraine severity and frequency (no meds helped), I began to have a different type of nightly extremely severe headache in the middle of the night that was unbearable. I visited a Headache specialist in North Carolina and soon after a move, in San Fran; I was still very sick and visited headache specialist in early 2020 at Mayo clinic. Under preventative treatments from my Mayo physician, I now have migraines that respond to acute treatment about 4 episodes per month, and noctural MILD headaches maybe 5 times per month. My life is much improved, and I am very seldom having severe GI symptoms with either type of headache or feeling nauseated and in terrible pain daily.

Dizziness is a conceran for many reasons. If you feel you are severely dehydrated or at increased risk for a fall or falling asleep driving--or might be experiencing inner earissues--please do see a physician (if not already done). I hope you can find someone to help who can offer some options for relief. It can be very depressing and debilitating.
