question: I have rashes on my hands, arms, neck, and less so on my legs.  The rash is much improved in the mornings and steadily worsens, getting very bad by the evenings.  Could it be related to cortisol levels?  I have always had very dry skin and had exema as a child which resolved as I entered adulthood until the past 9 months or so.  I am 44 years old.  I have also had cronic, though not debilitating, headaches for the past 15 years, which also seem wose as the day progresses.
