As a guitar player in a rock band, Manuel listens to loud music on a daily basis. According to research listening to music at 85 decibels or higher can cause hearing loss. Most likely after years of playing rock music next to a pair of loud speakers (which most likely played at 85 decibels or higher), it is safe to assume Manuel is suffering from an injury to his eardrums which explains why high-pitched sounds hurt his ears.
