Lets hope this is not too rude

a man walks into the doctors and finds a very young nun sitting at reception. she says name. he says Higgins, she says Trouble he says yep. she says no whats the trouble, i have to write it down. so he says i have trouble with my penis. the poor young nun suddenly faints flat out on the floor.
the doctor rushes in and sorts the nun out then takes mr higgins in to his office. he says look if you have a sensitive problem then just make something up to say to the nun and then you can tell me the real problem when you come in. The man says i will do that in future doctor i am very sorry to have caused a problem.
The next week he go's back to the doctor and the nun says name, he says higgins, she says trouble, he says yep She says no whats the trouble i have to write it down. he says erm it's erm my elbow, she says whats wrong with it ? he says i can't pee out of it.
