Is it permissible for a person suffering from an anal disease to expose his 'awrah (part of the body that must be covered) to a doctor?

Question:
He says: Honorable Shaykh, may Allah grant you success. A questioner says that he is suffering from a disease in the anus, and that this disease is increasing day after day, and that what prevented him from seeking treatment was modesty and the fear that exposing his 'awrah to a doctor is forbidden. So his question is: Is this exposure permissible for him?

Answer:
Yes, this is due to dire necessity. It is permissible to expose the 'awrah for the sake of medicine and dire necessity; there is no harm in it. Allah (Mighty and Majestic) says: This is general for everything that compels a person. The principle is that there is no prohibition; the principle is that there is no prohibition in the case of dire necessity. Yes.
