Hello. Is the rash raised? Is it all over your body or in specific places? Is it worse or better when anything specific is done?
I would suggest going to your doctor and suggesting that they do an allergy test. Maybe there is something that is causing you this problem that can be eliminated. You should use laundry detergent that is clear of any chemicals and use soap for sensitive skin until you have the doctor check out the rash. It sounds like a response to an irritant. Something that is irritating your skin which most commonly is due to laundry detergent or soap. I hope this has helped.....They can do a simple blood test or a skin test to test for allergies
