Im a 22 year old male have moderate pain at times in lower abdomen and sometims in pelvic area on movememts like ggetting up from chair or doing a sit up. I have had a 8 panel screen for stds 4 months post exposure I was placed on doxycline from doctor because my original symtoms were an itch in mornings and night in lower scrotum and anus . All my test results came out negative for stds. Was an igg blood test with urine. Wondering what else could be causing my pain??
Thank you. Have you any burning sensation during micturition?your pelvic pain is probably due to mechanical pain.  Do routine exam. Of urine & USG of pub region.
