Age-21 gender -female symptoms -i'm having burning urination from 7 months now along with mild difficulty in passing stools and brown and black hard covering on stools. These two symptoms started the same day and it happened due to intercourse. Sometimes I have mild pelvic pain and urethral pain. My urine reports are normal. I took many antibiotics but nothing worked but after taking niftas I was okay for some time but symptoms started again.
