WTF

doctors are almost certain her rash is actually shingles.  it is a virus that can become active during high stress.   they have ordered labs to confirm.  and will be agressively treating it because if it ends up in her eye thats extra bad.  catching it and treating within 24 hours minimizes the chance it will spread to her eye.   

from whatisshingles.com:

Shingles is caused by the same virus that causes chickenpox. After a person recovers from chickenpox, the virus stays dormant in the body and can reactivate years later, causing shingles. 99% of adults 50 years of age and older in the United States are infected with the virus.

Your immune system naturally weakens as you age, so your risk for shingles increases as you get older — even if you feel healthy. Almost one in three people in the United States will develop shingles in their lifetime, leading to about one million cases of shingles per year. Vaccination can offer protection against shingles. The Centers for Disease Control and Prevention (CDC) has recommendations on who should be vaccinated against shingles
