My son-in-law (currently serving R Sigs) has an **** fistula that's been giving him problems for 18 months. He's been medically downgraded. He's just been seen by a civvy consultant who says he can operate but there is a possibility of incontinence as a result, he has been seen previously and the doctor stated that it was like a labyrinth. This is not my area of expertise. He does not know whether to go for a medical discharge or what. Any advice please?
