I'm an 12 year Active Duty Air Force E-7 and have chronic lower back pain. In the last 2 years, I have been exempted from 2 of the 4 components of the last 3 Air Force Fitness tests. This year, I was attempting to take the whole PT test but with my back pain realized I will need an exemption on the 1.5 mile run. Is there a chance I will get MEB'd and discharged? I have no physical damage just chronic pain bad enough to keep me from running fast enough to get the time required to pass the test. I have also only been off and on a profile for about 8 weeks of the past year as I only get one for PT tests. Otherwise I can do my job fine.... This is my first post, so my apologies if it's in the wrong area or worded incorrectly.
