uck - how awful that you have to deal with this rash. I wonder if you would be able to detect under what situations does the rash appear .. I wonder if that would lead to a trigger getting identified. Does taking an oatmeal bath help when the rash appears ?? Oatmeal baths are supposed to help for chicken pox .. not sure if that is really true or not. I would be great to get some relief from the symptoms while you wait for the medical community to figure out what the rash is. Unfortunately, they don't know everything and it is really frustrating when they can't figure something out. Hang in there, hopefully you will get some answers and some relief soon.
