Im Currently Holiday And Im Unable To See My Dr

Im currently holiday and im unable to see my Dr until i get back so i need a temporary fix really.
I recently took a dip in the hotel swimming pool, after i got out and showered my foreskin felt dry, after drying it got incredibly itchy, i resisted as much as i could but found i woke up scratching, ive tried bathing it, keeping it cool, ive also read that cortizone would help but as soon as i applied it, it started burning so i washed it off, its subsided for now but i fear its going to ruin the rest of my holiday... any help would be greatly appreciated...
