Hello @ronyd and welcome to Mayo Connect. As one who has dealt with vertigo for several years, I can empathize with you. This is a difficult-to-treat problem, but some helpful therapies are available. I've also been told to limit the use of meclizine as it can have a rebound effect if it is used often.

Are you aware of Vestibular Therapy? Some physical therapists are specially trained in this vertigo treatment. You might consider asking for a referral for this.

Finally, for you and others in this discussion group, I recommend you view the posts in Connect's ENT discussion group where vertigo is discussed. Here is a link to those posts,

Many posts mention vestibular therapy, including terms like the Epley maneuver. @ronyd, have you discovered any activities that trigger the vertigo symptoms? For me, doing tasks that involve bending, and reaching up and down will activate vertigo. Have you discovered activities that might be a problem?

Neurologist wants me to try Phenergen for a week. Vestibular PT useless for me.
