If you get these painful red bumps, you may have dyshidrotic eczema
Triggers may include allergies, stress and frequently moist or sweaty hands and feet.

As per reports, people with contact dermatitis, atopic eczema, or hay fever have a higher risk of developing dyshidrotic eczema. The resulting sore patch of skin can have a tendency to become infected, thus delaying the healing process.
According to the Cleveland Clinic, healthcare providers aren’t currently sure what causes dyshidrotic eczema, and so there’s no surefire way of preventing flare-ups from taking place.
