    In a medical monitoring system, develop a function that identifies the next symmetric vital sign reading (where the number reads the same forwards and backwards) following the current measurement, to establish standardized calibration checkpoints for medical equipment. The function should take the current vital sign reading as input and return the next possible symmetric value that could serve as a calibration point.
