Nephew faking shoulder injury to get out of deployment?

My nephew, who is a marine, claims he received a rotator cuff injury a year ago while on his last deployment. He has had it looked at by military doctors, who claim there is no major injury. Recently, he went to a civilian specialist, who gave him a written diagnosis that he needs to have rotator cuff surgery immediately. My nephew is due to deploy to Afghanistan within the next month and now believes he won't have to go because he has this 'excuse' from a civilian specialist. He plans to have the civilian specialist perform the surgery and then go back to his hometown to take convelescent leave for the next several months. I have never known anyone with a rotator cuff injury, but it appears to me that he has full use of his shoulder and he doesn't appear in any pain. I've seen him lift his 3-year old daughter and put her on his shoulders without a wince. Would this be possible if you had a rotator cuff injury. I should also note that the civilian specialist he saw is a 'friend of the family'. This kid is a piece of crap and has cheated the system his entire life. It's all he knows how to do. I am hoping this time, karma kicks in and he gets his due diligence. Will the military heed the excuse from the civilian specialist and not deploy him? Will he be able to get several months of convalescent leave? Will the military allow a civilian surgeon to perform surgery while he is in active duty? Please tell me this kid is going to get what's coming to him!
