So i was at MEPS couple days ago, got DQed for flat feet. Doctor diagnosed me with flat feet and asked if my feet hurts when running, i said no. Then after some questions she asked if my leg ever hurts when i run, i said no, but when i started running, my ankle did hurt for a while then it no longer hurting. She associated that ankle pain with flat feet. She also said i can apply for waiver and my liaison told me i could write a letter of recommendation explaining that the pain was because i never did runs so my leg wasn't used to it. What are my chances on getting my case waived and cleared for enlistment? Is my case even waivable?
