Current medical holder. No official diagnosis, but doctor is considering an Ankylosing Spondylitis diagnosis. I do know that AS is now included in the Arthritis CACI profile. Question 1: If officially diagnosed, do I wait until my next medical to report it? Question 2: The use of Humira is listed on the arthritis CACI as acceptable with a 4 hour no-fly period. If doctor prescribes Humira and no other medication, do I need to get an FAA approval first, or do I wait until my next medical renewal to submit all the CACI required information? Question 3: Am I able to continue flying until my current medical expires without notifying FAA of new diagnosis and/or taking Humira? Do I need to notify FAA or stop flying.
