Agony!!

Im super super sore and itchy down below, ive tried canestine duo thrush cream and drunk cranberry juice (i got told cranberry juice helps?) but it seems to be getting worse! I wear pads because im a big girl and sweat quite abit down there but i do wash with water down below and dont use anything perfumed! May sound silly but i dont feel comfortable without a pad cos of how much i sweat, and i dont feel comfortable sleeping without knickers on incase i sweat or dribble on the bed, i know i sound silly but are there any other options that can help? Rather not go back to dr as she had a look inside last time and it killed so so much 😭😭
