If this is the first time you've had botox they may have started you on a lower dose, when are you due to go back for your next treatment? Have you thought about contacting the hospital and discussing the lack of the effect, I'm no expert but I would think you would start to feel benefits by now. I've had Botox on several occasions and your body can get become a climatized to it. They may increase the dose depending on how successful it was or bring your next appointment forward. But they won't make any changes until you give them some feedback.

@sarahBridport thankyou for your reply. She said she would see me in 9 months. I reached out to the continence team a few days ago, the advised me to start ISC twice a day. They will be calling back next week to see how I'm getting on. Okay brilliant thankyou
