Many thanks for taking the time to read and review.
The expression 'wen' is one I've wondered about using. I knew it as something that the writer William Cobbett used to describe London. A wen is a sebaceous cyst and not something you'd want - a pus filled sore. I'm leaving it as it has the feeling of the time and of the speaker - a doctor would probably know the reference and the meaning. Other than that, I'm glad you liked reading it. Thanks again for the thoughts on the writing. Good luck with your own.
