What Causes Red Foreskin And Splits On Tip Of Penis?

MY FORESKIN IS RED AND SMALL SPLITS AROUND THE VERY TIP END AND WHITE RESIDUE UNDER IT, THIS HAS HAPPENED ONCE BEFORE BUT IT WENT AWAY IN A FEW DAYS BUT THIS TIME HAS BEEN A WEEK OR SO. WHAT DO I DO? I WAS RECENTLY IN HOSPITAL FOR PANCREITUS WOULD THAT HAVE ANYTHING TO DO WITH IT?
