My FEO has just contacted my doctors mine is the durham area i asked the feo if this was routine he said if you put anything at all in the medical question box on the form they will contact your doctors every time
They send your doctor a form to be filled in to check you have no mental illness and what ever condition you have wouldn,t put you or others at risk from you owning a firearm.
by the way i just put i take medication for high blood pressure and they still contacted my doctors
