Thank you so much for the help.  We think it was caused by over heating and a high level of stress.  
Thank you again for all your help.

Not sure, it could be a number of things, try taking an antihistamine, like benadryl, this should stop the itch. If it continues see your MD. Hope this helps.

Hi, welcome to the forum, this seems to be a form of allergy. The allergen can be in the form of hot water bathing (temperature factor), low humidity environments, xerosis (dry skin), overheating of skin, and exposure to solvents and detergents.

Avoiding these situations is helpful for acute flares as well as for long-term management.

In such condition maintenance of adequate hydration of the skin is quite important. Which includes thick creams (eg, Eucerin, Cetaphil, Nutraderm), which have a low water content, or ointments (eg, petroleum jelly, Aquaphor, Petrolatum), which have zero water content, are better.

Along with above measure use of anti histamines and corticosteroids will help to reduce itching (if present) of the skin as well as rash.

I suggest you to consult dermatologist. Take care and regards.
