I had sex with a girl- anal sex- five month ago and after one week I had severe infection, difficulty urinating and pain in penile area and bladder, burning, all there is, the doctor ordered some tests but most came back negative, I'm a masturbation addict, I use to do this like more than 5 times per day, not just that I use to hold it and not ejaculate, which my doctor said it affected my prostate, the end of the diagnoses I was diagnosed with Chronic pelvic pain syndrome- chronic prostatitis- they prescribed me antibiotics but i do not do very well with them, so I decided to let it go on its own, and it did, but lately this month and the month before I've been noticing severe pain in my both flanks and back, it tends to get worse If my bladder, when I urinate the pain would go and then come back, no fever, but really fatigued and exhausted, and my urination is not at all hard but I feel that my stream has gone weak, my urine sample is normal but did not do any culture, my sonar image is normal also my CAT scan which was done 2 month ago, my blood work is fine except for the CRP which came back a little high, my question is can a prostate bacteria or a bladder infection spreads to the ureters and hence to the kidneys? the pain in my kidneys area is strong and constant and gets worse much worse if i masturbate, Cipro antibiotic caused me to have an allergic reaction, so I suppose they gonna give me something else..anyone can relate to this? thank you very much and god bless you all.
