How do I request a Medical Board in the Army?

Ive been in the Army for over 2 years and during my time in the service I've had to undergo 2 surgeries. One surgery was to repair a torn MCL and the other was to repair ruptured ligaments and tendons in my foot. Since 2009 I've mostly been on a profile of some sort due to those injuries. I was doing physical therapy but it didn't help like they thought it would. Last year I was diagnosed with Bell's Palsy, and 2 weeks ago I was diagnosed with Gout. Both of these conditions put me at a greater risk of heart attack and stroke. So how do I go about requesting to seek a Medical Board?
