There are many possible causes of foot rashes. Athlete's foot is one of the more common causes. Additional causes include irritant or contact dermatitis, allergic rashes from shoes or other creams, dyshidrotic eczema (skin allergy rash), psoriasis, keratodermia blennorrhagicum, yeast infections, and bacterial infections.
Foot itch caused by a medical condition is related to an increase in the neurotransmitter serotonin. For this reason, doctors often prescribe anti-serotonin medications to treat itching. Medical conditions that cause itching feet include: 1  cholestasis, a liver disease that occurs during pregnancy. 2  Hodgkinâs lymphoma.
