This seems likely: A dermatology consult is advisable if you have disability. If this is dyshidrotic eczema, it's manageable. In the meantime, have you tried applying topical cortisol to your soles before bedtime each evening? Do this only if it's okay with your physician. There are a host of interventions that might help you, from compresses to a low-zinc diet; i'd be interested in what works.
