Several things can cause vertigo to flare up.
Some things that can cause vertigo to flare up are, ear infections, head injuries, lack of hydration, being dehydrated, ear surgery, laying in bed too long.
Also laying in the wrong position can also cause the vertigo to flare up and if you are in bed rest and laying in bed too long then vertigo can flare up.
Lack of water and hydration can cause Vertigo to flare up because you can get dizzy when you do not have enough hydration.
On of the symptoms of dehydration is dizziness so if you're feeling dizzy and have not drank any water or other hydrating liquids in awhile you should drink water.
Drinking water should be done before you're thirsty because dehydration when it gets severe enough can kill you.
Vertigo is a lifelong illness because there are no cures for Vertigo.
When someone has Vertigo they will most likely always have the Vertigo for the rest of their lives.
Treatments for the Vertigo can help ease the symptoms of the Vertigo but there's no full on cure for Vertigo.
My Grandma suffered from Vertigo for 30 years before she died and although treatments helped with her Vertigo she had the Vertigo for the rest of her life.
So in her case Vertigo was a lifelong illness.
Vertigo usually comes and goes and may come for a few days and then go away for a few days.
So you may not experience Vertigo everyday but it will come and go for the rest of your life.
