I had unsafe sex with someone a long time back. I got checked for all STD's and the report is clear. But I caught some bacterial infection which causes itching while urinating and sometimes otherwise inside the shaft of the p***s. It comes and goes and when its itching even rubbing wont make any difference. I saw a doctor and was recommended Norflox. I took it for a week and the symptoms died down to a great extend but have not gone away. I still feel itching sometimes and there is sometimes slight redness on the tip of my p***s. What do I need to get rid of this bacterial infection once and for all?
