Another thing to watch for if you are allergic to latex is feminine products. There is nothing on the labels that tells you there is latex in them, but after over a month of misery that the doctors couldnt figure out, and some research on the web, I found the culprit!
It will take a while for the damage to go away if you were at the weeping blister point. The blisters themselves will heal up in just a day or 2 from the steriod cream, but I have found the redness/tenderness/mild itching to be lasting about a week after all contact is stopped. I would also be watchful of the steriod cream, it seems to be kinda harsh, and can inflame other dermatitis issues.
The others are right about the antihisamine. Benadryl is good. It helps with the itching.
