The insides of my wrists where they meet my hand burn and itch with no visible symptoms. any idea what it could be?

Not certain : Likely skin irritation. Sometimes such can respond to topical steroids

Itchyness (pruritus): Pruritus is a common disorder that affects the skin. Common causes include dermatitis and dry skin. In the absence of visible lesions pruritus might be secondary to underlying systemic disorders including cholestasis due to impaired secretion of bile. It typically begins with an acral distribution involving the palms and soles. Associated conditions include liver disease, also common in pregnancy.
