Hydrocortisone iodiquinol is not nearly the strongest anti-yeast
medicine there is, and the hydrocortisone may be aggravating yeast
, so if that's what you've been using all along, I'd try clotrimazole 1% (over-the-counter). Alternately, this could be balanitis (irritation), in which case a stronger steroid for a while might be what you need, but I would try the yeast cream first. And I'd arrange to see the doctor again, or another one. Whatever you have, it's curable.
