You are right, you are having chilblains
, also known as pernio.
It occurs after exposure to cold.
It is an abnormal reaction to cold.
There is constriction of capillaries in skin.
It may be idiopathic, i.e. without cause.
Or there may be some cause.
Familial tendency, smoking, connective tissue
diseases may be associated with chilblains.
It may be selflimiting.
Warm water soaking may improve the condition.
and antibiotics may relieve pain, burning and itching.
Vasodilators like nifedipine
and pentoxyphylline may be helpful.
If you are smoking, quit it.
Keep the skin moist for prevention.
I hope you got my answer.
