Left testicle, bladder and lower back pain

morning all, new to the forum and really just interested to know if anyone else had suffered or come across these same problems. i had a feeling come on msybe 8 weeks back as if I had a UTI on its way (have suffered them previously due to history of kidney problems). Received antibiotics although urine showed no infection but the pain got worse and now i have pain in left testicle and lower abdomen. Im up more frequently at night for the loo and the testicle and lower back pain are much worse at night time. up to now ive had cyscoscopy which did show some scarring in bladder although dr didnt suspect anything sinister, and a CT Scan a couple days ago which i am awaiting results for. im on cocodamol for the pain but hoping they can diagnose me soon with the ct results. any one had anything similar? a few people have mentioned proststitis and cystitis so would be goos to get peoples thoughts. thanks
