Hello and welcome to HCM,
The presence of vaginal discharge
, dysparuenia (pain after having sex), lower back ache and apositive vaginal swab for streptococci suggests infection of the genital tract with streptococcus
Painful urination suggests concomitant urinary tract infection
You need to take antibiotics after drug senstivity.
The infection will clear away after taking antibiotic.
Thanks and take care.
