Agonising thrush😭😭

Unfortunately a side effect of my diabetic medication is thrush, and normally it isnt that bad and canestine thrush cream and vagisil thrush cream normally gets rid of my thrush quickly but not this time... im in that much agony and my tummy feels so swollen and ive scratched myself raw i want to cry! The bit ive circled on this pic is where its really itchy too, is it normal for it to be so painfully itchy that low down? And any advice on how to quickly get rid of the painful, burning, itchiness please 😭😭 got doctors on Wednesday so gonna bring it up with him but need something to help now as its driving me mad and causing me so much pain 😭😭
