I get a jury duty summons every year like clockwork. Usually, my jury group winds up not even having to show up. But, in the past decade, I've had to go in 2-3 times. One time I was excused by the judge on a 2 month trial, after filling out the questionnaire. But at that time I was using a cane and wearing a CAM walker on my foot, so I was a mess. The other times were short trials and I thought I would be excused by telling the judge I have chronic diarrhea and no colon, but I was told, "no problem, just raise your hand and we'll take a recess." One case I got in the jury box and was finally cut loose by the defense attorney. The other case, I was sworn in and they dismissed the case the next day. Once in a while my summons gets "lost" in the mail...but, I don't recommend that.
My husband has UC and is an attorney. He gets a summons every year too. This year he got stuck on a two week case. Put his schedule in a real bind.
So, I am not sure there is much for you to do other than hope for the best.
