Get Raynauds Disease Treatment Online

Raynaud's disease (also called primary Raynaud's) occurs on its own without an underlying condition. Raynaud's phenomenon (secondary Raynaud's) is associated with autoimmune or connective tissue diseases such as scleroderma or lupus. Both involve vasospasm of the small arteries, but secondary Raynaud's tends to be more severe and requires treatment of the underlying cause as well.

The most common triggers are exposure to cold temperatures and emotional stress. Even minor cold exposure, such as reaching into a freezer or holding a cold drink, can provoke an episode. Stress-related vasospasm can occur even in warm environments.

During an episode, affected areas typically turn white (pallor) as blood flow is reduced, then blue (cyanosis) due to oxygen depletion, and finally red (erythema) as blood flow returns. Episodes are often accompanied by numbness, tingling, or a burning sensation.

Calcium channel blockers such as nifedipine, felodipine, and amlodipine are generally well tolerated for long-term use. Common side effects include headache, flushing, and ankle swelling. Your Doctronic physician will review your health history to ensure the chosen medication is appropriate for you.

Yes. Keeping the whole body warm, wearing gloves and insulated footwear, avoiding smoking, managing stress, and limiting caffeine can all help reduce the frequency of episodes. Lifestyle measures are usually recommended alongside medication for best results.

You should seek in-person or emergency care if you develop persistent pain, non-healing sores, or ulcers on the fingers or toes, as these may indicate critical ischemia requiring urgent evaluation. Severe or worsening secondary Raynaud's may also need specialist assessment by a rheumatologist or vascular physician.
