Pelvic and Leg pain. Please revert.

I'm having intense abdominal and pelvic pain since 3 weeks. The pain radiates down to my legs and is maximum in inner thighs and buttock area. The front and back of my lower abdomen hurts consistently and is painful when touched. My back pains and the pain radiates down to my legs. The pain gets somehwhat relieved after taking zocef 500 and dolowin plus but is not going away. It gets increased frequently. As soon as the medication's effect fades the pain starts surfacing again. The left and right side of my abdomen pains when touched. The pain is spreading upwards with time. Please recommend a quick and effective solution. I'm unsure whether the pain is only related to uterus infection or is it something else too. I've attached my recent ultrasound report. Please revert.
