Plural of analgia; multiple instances or types of pain insensibility or conditions involving inability to feel pain.
Standard English plural formation of analgia with the -s ending. Each instance of analgia represents a specific case of pain insensibility.
While technically valid, you almost never see 'analgias' in modern medical literature because doctors now prefer the term 'analgesia' and rarely pluralize it—we say 'instances of analgesia,' not 'analgesias.'
