Oh was just going to answer your question EllenMay. I have had to have one (firstly six monthly) 12 monthly and for the past 4 years. I found that a diazepam taken an hour or two before maybe a painkiller helps. I just feel like I'm about to wee but thats the only discomfort.
After my 3rd cystoscopy which was performed (and it was a performance) by a trainee (he tried three times and three times released the saline all over the couch) the Dr showed him exactly where to put it. (They were both peering at my bits and discussing which was my urethra) While I was getting my undies on the Dr said to the young guy "The next one will be easier, its a man and we can put much more pain killer cream on as too much makes the ladies a little incontinent", I looked around the curtain and said "Damn the incontinence, put more cream on and hand me a Tena pad."
Honestly though the team are great and I have another 6 years of these. Glad it want Ok for you.
