Hi
It seems that it might be some dermatitic or eczematous
rash. A reddish smooth
rash is described as a macular
rash. It can be caused directly or indirectly by stress, allergic reactions (hives) heat or sun exposure, bacterial, viral or fungal infections, underlying medical illness or medications. Scaling, blister formation, itching or ulceration may or may not accompany the rash.
