Could sjogrens contribute to sporadic bouts of vertigo lasting a few days at a time? what treatments are recommended in addition to meclozine?

Sjogren's: Can indeed cause neurological symptoms, but more commonly affects hearing, not bouts of vertigo. More likely you have an inner ear problem such as Meniere's, endolymphatic or perilymphatic fistula, or otolithic dysfunction such as benign paroxysmal vertigo. If you did have true Sjogren's, and severe neurological issues, cyclophosphamide might be a useful medication, but Plaquenil (hydroxychloroquine) and MTX also?
