Actually, when you're dealing with Dr. Kendall, after an illness, you can tell him when you feel "well enough" to go back to work. What that means is if you want or need some extra time off, he'll be more than happy to support you in that. As well, depending on what you went out for, his office can facilitate your paperwork with the FAA, to allow you to resume your flying duties as quickly as possible.
