Lichen simplex chronicus or neurodermatitis is related to anxiety disorders, causing the skin to feel mildly irritated, explains Podiatry Today. However, an object rasping over the skin can cause it to itch, which then eventually leads to redness, skin damage and red bumps along the skin. Topical steroids and antihistamines can help to relieve itching and treat the problem.

Atopic eczema and contact dermatitis can produce rashes on the top of feet and are caused by an allergic reaction or a sensitivity to an allergen, notes Podiatry Today. An individual with the former normally has allergies, asthma or hay fever while the latter is an allergic reaction to a specific substance such as soap, rubber or dyes.

Tinea pedis or ringworm is a fungal infection that commonly affects the feet, creating dry, scaly skin, according Podiatry Today. Psoriasis is an autoimmune disorder that can occur anywhere on the body. It causes severe itching.
