Calcification

Calcification is the sudden, rapid deposition of minerals in the bloodstream onto bones. Side effects include dizzyness, blurred vision, muscle spasms, and muscle weakness. Bacta tank immersion or bed rest can cure it; if untreated, the affliction can become permanent.

Calcification is casued by exposure to high-strentgh electric fields. It is also one of the aftereffects of exposure to Force lightning; Luke Skywalker suffered calcification after the Battle of Endor; it is unknown whether Palpatine also experienced it after his confrontation with Mace Windu.
