Feelings of dizziness are usually short-lived, but some people have long-lasting dizziness and balance problems. The most common cause is a simple viral infection, such as the common cold, spreading to your inner ear. Although your immune system gets rid of the virus quite quickly, your balance organ (the vestibular system) might have been damaged. You may feel dizzy until your brain can adjust to deal with the damage.
This sort of balance problem is usually helped by vestibular rehabilitation physiotherapy, which includes head and balance exercises.
Other health conditions not related to the inner ear can also cause balance problems, so make sure you see your GP.
