Pain when urinating

I would contact the hospital at which you had the radiotherapy and either speak to the radiotherapy department or your consultant's secretary to ask your consultant about this.

I can't think of any reason why it should be linked to the radiotherapy, which would have minimal effect (if any) on the lining of the urethra.

(*unless the PCa had local spread towards the bladder?)

But where is the pain? bladder, 'plumbing' or penis?

Is it worse at a particular time of day?

Is it eased by drinking plenty (2-3L per day)?
