I've become increasingly sensitive to both poison ivy and fire coral with each exposure. My reaction to fire coral started as nothing but grew really intense a week later (red welts that itch like crazy). Hydrocortisone cream and benadryl did nothing, and after two weeks I went to the doctor when I was scratching so hard I thought I was going to rip my flesh. Was given a shot of methylprednisolone and benadryl and had immediate relief. He also gave me an Rx for oral prednisolone with instructions to reduce the dosage over the next week. The itching never came back and the redness, swelling, and welts were noticeably down the next day, and gone after a week.
Each person's reaction to allergens can be wildly different. And remember that the "sting" comes from barely visible hairs extending out from the hard surface of the fire coral; you don't need to smash into it, a light brush is more than enough.
