Unless Don had a laparoscope appendectomy procedure he will most likely be unable to fulfill his gig schedule for at least 2 to 3 weeks. The most important thing is to make sure no infection occurs and to get complete rest for a speedy recovery of course.
Glad you caught it time Don.
A ruptured appendix would have complicated matters a little, to say the least.
Rest up and get well soon.
Oh, and try and keep your hands off those pretty nurses okay?
>> Just kidding.
All the best,
