Dancing with the Stars performer Val Chmerkovskiy was recently sidelined while on tour in Peoria, Illinois, after experiencing severe dizziness—symptoms doctors traced to benign paroxysmal positional vertigo, or BPPV. The condition, caused by loose calcium crystals in the inner ear, has also affected Bloomington resident Dave Williams for decades. Treatment methods have come a long way, from basic medications to advanced technology like diagnostic goggles and virtual reality systems at OSF HealthCare. Specialists at OSF HealthCare explain that this condition is caused by tiny crystals in the inner ear moving into the wrong area, disrupting balance and causing severe spinning sensations. Technology has advanced rapidly, with high-tech goggles now allowing therapists to pinpoint trouble spots and guide effective treatments, such as the Epley maneuver. For long-time sufferers like David Williams of Bloomington, these innovations mean quicker recovery and fewer surprises.
