Kathleen,
Infestations from mites can pass from animals to humans, so perhaps the lady
with broken skin under her breasts has picked up something from the goats.
Maybe she should call the vet :)

Anyway, several thoughts:  People can get away with sweating and having
their skin rub together so long as the skin doesn't get broken and become
infected.  Then it's hard to heal unless treated.  In general, a small bite
or irritation from contact with something toxic (are the goats being
dipped?) gets scratched, then infected, and until the infection is healed,
the sweating and chaffing just continue.

Hot water soaks make eczema worse, but cleanliness keeps infected areas from
getting worse.  I'd suggest daily  brief, cool water showers.  Follow with
application of anti-fungal cream and maybe some cortisone cream to reduce
inflammation.  A brief, cool soak in a tub with either vinegar or baking
soda can be useful.  She might want to remember to keep fingernails real
short, and wash her hands carefully after tending to the goats and certainly
avoid scratching that area with dirty hands.
