Cure for severe itching on the foreskin of my penis

For the last 15 days, I have been having severe itching on the foreskin of my penis and sometimes on the head too. It is ver embarrassing as sometimes the itch comes right in the middle of a meeting/public gathering. I have tried using coconut oil, Boroline, Nivea etc but it is just not getting cured. The skin gets all roughed up/fissured on rubbing and now I have open wounds on the foreskin. The skin after drying of ointment gets puffed up and develops solid wrinkles much like back of garden lizard or a python. It softens up on apllication of warm water but then itching returns in 5 min. I am quite troubled by this and am seeking some cure. Yesterday I tried Betadine solution also, will check and update results today.
