Episiotomy & thrush

Elsie
Hi ladies
I gave birth via vontouse which required an episiotomy and stitches (9 days ago)
I feel generally that they are healing well but I think I'm getting thrush and/or a bladder infection.
I've got pain in my urethra and also starting to itch. I'm pretty sure it not my stitches itching and more likely to be thrush. Can I use cream such as canesten so soon after giving birth? 
Amy advice would be great
