Vertigo is a symptom characterized by a disorienting sensation of apparent motion (usually spinning), which can make life challenging. A common cause is Benign Paroxysmal Positional Vertigo (BPPV), which occurs when tiny crystals in the inner ear become dislodged and move into one of the vestibular canals. These loose crystals interfere with your sense of balance, causing symptoms like vertigo, nausea, and instability. Actions like rolling over in bed or looking up or down can trigger episodes
