Was given 400mg cefexime and 1g azithromycen for urethritis but still dont feel quite well 10 days later. bladder pressure slight perenium tenderness and tingling on the outside skin of penis/scrotum these come and go from day to day?

If you had normal urethritis symptoms (discharge, discomfort or pain when urinating) and those have cleared up, your urethritis is cured. Urethritis doesn't cause bladder presssure, perineal tenderness, or tingling. Also persisting urethritis symptoms are not intermittent ("come and go"). This sounds like increased awareness psychologically. But see your doctor if you remain concerned.

Try soaking in warm/ hot water, drink plenty of water and pl see a Urologist- you moght need aculture and smear exam of the urethra too. Hope you do well.
