I had a swollen right testicle which was treated by ciprofloxacin 500g twice daily. The swelling went and the pain in the testicle reduced but then my left one started to hurt, is that conman for the infection to swap sides. I also have pain in my lower back and lower abdomen and very painful headaches. The doctor didn't seem to bothered about it or even check it over. They have prescribed me another 10 day course of ciprofloxacin. Am I worrying to much about this or is there anything else I should be doing about it
