Make sure to wash your clothes, jacket, boots, etc. You may be picking up the oil from your jacket or something and continuing to break out because of it.
There isn't much of a cure for it except time. Wash with a detergent to get the oils off and keep it from spreading. Use lotions such as Calamine to dry up the oozing and keep it from itching. Don't scratch at it. It just has to heal. Give it a couple weeks.
