Wow, if it's hurting you this much then maybe you should talk to the judge; don't they have alternates for jurors? Sorry, I know little of the law, but when I get a jury duty notice I get a doctor's notice and secure an excusal, in the interest of justice. I'm not sound to serve on a jury. My wife was a juror in a trial last year and it was enormously stressful for her, and she's steady as a rock. There must be protocol to replace a juror in the event of illness.
