As I'm sitting here waiting for the doctor to call me back... I'm getting married in a little over a week. On Monday, I must have come in contact with poison ivy as I woke up Tuesday with a nice poison ivy rash. Wednesday as it took a greater presence on my face, I called the doctor, had an appointment, and was prescribed prednisone. Took 3 (20mg) pills first 2 days, 2 (20mg pills) today and tomorrow, and then 1 the next 2 days. Since Wednesday, I feel like the rash has spread and my face actually looks more red than the other day and now it's cover more of my arms than before (worse today than the last 2 days--2 days ago there was only a small spot above my wrist on my right arm, today it's covering about half of my right arm). Who has experience with prednisone? How long does it typically take to start working? I'm taking lots of benedryl to try and keep the itching in check, but... Now if only the doctor would call me back! He originally told me I should start seeing relief in 24-48 hours, but I'm just past the 48hr mark... On another note, who gets poison ivy a week and a half before her wedding? Me. I'm sure stress isn't helping, but I wasn't stressed at all about the wedding before the poison ivy!
