help with hemorrhoid please

Anyone have any experience with external hemmerhoids? So I've had this external hemmerhoid for about a year and it usually doesn't bother me but lately it's getting worse and I need some advice on how to treat it. I've tried hydrocortisone cream just on the outside because the bottom says not to put it actually into your anus, but it just isn't working. What kind of doctor can I go see for this? Any other home remedies to try? And what should I expect if I see a doctor?
