Setting: Early twenty-first century, an alternate universe in which the Russian Empire has conquered most of Europe and Asia. Takes place mainly in St. Petersburg and London.
Searched: "hemophilia," "hemophilia treatment," "clotting agent infusion," "clotting agent," and variations. Also tried the alternate spelling of "haemophilia." Read several books on genetic disorders in the school library's reference section and checked out a few medical databases.
I've learned all I could possibly want to know about the symptoms of hemophilia, the history of hemophilia, how it's passed down, etc. But all I can get when I look for how to treat hemophilia is 'an infusion of a clotting agent,' or 'an injection of a clotting agent.'
I need more details. Does said injection have to be done by a doctor or can the hemophiliac do it himself? If they're preventative injections, how often should they happen to be effective? How much does the injection hurt? Any information whatsoever would be very helpful.
