Hi there ~
I understand your concerns. The red spots which itch and tighten your knuckles when hand toes get cold
are related to your allergies. I also think that you might not have a circulation problem. I feel like you should avoid the allergen which is the cold or warm temperature changes. I believe that you do not have hives
, you just have an allergic reaction
. Please avoid the allergen and distract yourself from it. Loratidine
is useful in allergies as is levocetrizine and monteleukast. I hope this helps.
Take care and have a lovely day!
