Valtrex Feels like it made symptoms worse

Hi i have genital herpes. and i’ve only had one outbreak which is the initial one. A LOT of crazy ass pain! So glad they told me that the first one is the worst. So recently i thought i had a UTI because of a little tingle when i went pee. I checked down there and didn’t see any bumps but i wanted to be sure so i went to my lady doctor. she said she spotted one sore that looks like It already popped. she prescribed me Valtrex bc she believed It was just an outbreak. however now the burning is worse when I pee and i’m just so uncomfortable after i pee. i’ll sit on the toilet until i find strength to wipe and go about my day or night. has this happened with anyone else? please don’t comment rudely. this is only my second outbreak.
