I am a 76 yo male. What may be the cause of an upper body rash , looks as a sunburn, and an itch on my left breast. No bumbs nor any sores. The only change in my ingestion in the days immediately preceeding , was a trial of using coconut oil with my cereal... only used a tablespoon or so. it is now three days and the rash is still there... Could a reaction to coconut oil cause this.?
