if this is a new condition it could be a contact dermatitis. this means that your skin is reacting to something it has come into contact with that has irritated that portion of your skin. while it might not be poison ivy you could have a sensitivity to something else. see if you can go back and figure out what might have set off this skin condition. in the meantime keep it clean and dry. apply a small amount of over the counter cortisone cream to see if that helps the itching.
i have itchy bumps on my forearms and hands that look like poison ivy but they don't ooze. what could it could be?
