you really need to see a doctor... Rash can be caused by many facotrs. A complete medical history will need to be taken and possibly a biopsy of the rash. In the meantime, benydryl may help alleviate the symptoms until you can be seen (but it can make you sleepy so don;t drive when you take the benydryl). Hope this helps.
