You may have dyshidrotic eczema (I have it, too, and it's no fun.)
from WEB MD: Small, itchy blisters on your palms and along the sides of your fingers could be signs of dyshidrotic eczema. This skin condition can also make blisters pop up on the soles of your feet or on your toes. Dyshidrotic eczema mostly affects adults ages 20 to 40, and it's twice as common in women as men. You're more likely to get it if you have allergies like hay fever, a family history of dyshidrotic eczema, or other forms of eczema.
Dyshidrotic eczema can be mild or severe.
Several things can set off dyshidrotic eczema, including:
- Stress
- Contact with metals like nickel, cobalt, or chromium salts on your job or from things like wearing costume jewelry
- Sweaty or wet hands and feet
- Warm, humid weather
- HIV infection
- Certain treatments for a weak immune system (immunoglobulin)
This condition isn't contagious. You can't catch it from touching someone who has it.
