Sounds like some of the signs
of Chronic Fatigue Immune Dysfunction Syndrome. The
chemical exposure that I suspect for that is 2-butoxyethanol
and from the age she is, she is classified as a baby boomer,
right? (Singular health issues can be late to show up birth
defects from a parent poisoned by this chemical such as WWII
soldiers or a parent who worked in manufacturing)
So if she has her own
direct exposure, she should be asked about fatigue, and
doctors should look for the extra things that would find the
fatigue of this chemical ... I would call it 'civilian gulf
war syndrome'
At any rate, vapors in eyes
is the major exposure. The chemical is in paint, it is
in cleaning products (has she started using new cleaning
products?) .... and you can get it 'second hand' by being
around someone else who has too much exposure (Their
respiration with chemical can get into others' eyes)
Ask if she recalls
diarrhea, sniffles ... or severe flu-like symptoms.
Ask her about these
symptoms (use any CFS, FM, CFIDS
checklist) mine goes heavy on what to look for over time ...
