What are the symptoms of Raynaud's syndrome

Symptoms of Raynaud syndrome include paroxysmal pallor, paroxysmal cyanosis, paroxysmal flushing, pain, paresthesia, etc.

1. Paroxysmal pallor

is the most common symptom of Raynaud syndrome. The fingers or toes suddenly turn white, which is caused by a decrease in blood supply due to vasoconstriction.

2. Paroxysmal

cyanosis changes from pallor to cyanosis, which is caused by further constriction of the blood vessels, resulting in oxygen deprivation.

3. Paroxysmal

flushing changes from cyanosis to flushing, which is caused by vasodilation and increased blood supply.

4.

Pain may occur in the fingers or toes, usually during or after the attack.

5. Paresthesia may

occur with numbness, tingling, burning, and other paresthesia in the fingers or toes.
