Vertigo

Mine isn’t a neck or back issue. It’s not the crystals either. I’ve done all the exercises for that at PT and at home. Therapist thinks it’s a nerve in my inner ear that’s causing it. I’ve taken steroids, antibiotics, decongestant and antihistamines. Just can’t shake it. It will go away briefly or half way but not all the way or permanently. Thanks for the input guys.
