Hello sir , I am 22 yrs old & I had swelling on the foreskin of my penis for which my doctor prescribed cetrizine , doxycycline hyclate tablets & Lobate gm ointment (i had no idea that it contains steroid) .After 5 to 6 days that swelling or inflammation was gone . BUT now i guess there is ulcer or sore on the tip of my penis(not the foreskin) .Now My doctor has prescribed CIFRAN 500 & Doxycycline .Is it balantis or something related to syphilis ?? what should i do now ? I have applied a little Lobate ointment thinking it will stop the pain,should i stop using that. It looks something like this pic http://intimatehealthhelp.net/wp-content/uploads/2012/08/syphilis-sore.jpeg . Please help me... What is the proper treatment ?
