Dermatitis: It sounds more like a skin reaction or inflammation- possibly an allergic reaction. See your local podiatrist for diagnostic evaluation and treatment.

See a podiatrist: Eczema, dermatitis, psoriasis, tinea infections, dyshidrosis can demonstrate an appearance consistent with what you described. Have a doctor diagnosis this for you, and work up a treatment plan. Usually this involves prescribed topical medications.
