Red spots, itchiness, tightness on knuckles, occur when hands get cold, similar occurrence on toes. What is the cause?

I have Red spots on my knuckles that feel tight and itchy. They only come out when my hands get very cold or when I switch from a warm temperature to a cold temperature. When I press down on them you can quickly see my finger print and it disappears. I also sometimes get the same reaction to the toes on my feet . Could it be an allergic reaction or a circulation problem? Could it be Hives or Eczema?

Thanks for writing to us.
The red itchy spots are likely to be due to vasodilatation. The temperature changes can trigger such a response. It is harmless finding.
I hope this information has been both informative and helpful for you.
