I have a 'contact dermatitus' rash that appears to be from Poison Ivy (no idea when I was in poison ivy so not really sure what it is). I developed a fairly severe reaction/ rash and went to urgent care (swelling face as well as large rash area). I was prescribed predisone, and given a cortisone injection. 4 days later the rash had not dissipated so went back to urgent care and got another cortisone shot and floucinolone cream. My face swelling dissipdated and the first part of rash is fading quite nicely, but here is is more than a week after the second shot and I am stlll itching, and seem to be developing new little spot rashes over my legs and arms. I have washed everything and I am no longer in the area of the country where I developed it.
My question is should I give the meds a few more days, or should I assume I am having continued histimine reactions and go back in?
How long does it generally take for the predisone and creams to resolve poison ivy? (I am on day 11 of 14 of the predisone, and 8 days of cream. 11 days after first cortisone shot, and 8 days after second one.)
