Hello dear. Welcome to Healthcaremagic. I read your query and I understand your concern. It looks like you are suffering from Raynaund phenomenon that occurs because of spasm of blood vessels. The cause of Raynaud s phenomenon is unknown, although abnormal nerve control of blood-vessel diameter and nerve sensitivity to cold are suspected of being evolved. Management of Raynaud s phenomenon involves preventing the spasm of the blood vessels by protecting the fingers and the toes from cold, trauma, and infection. Patients with persistent or bothersome symptoms may be helped by taking oral medications that open (dilate) blood vessels. (Sometimes these medications are decreased or eliminated when the environment is warmer, such as during summer months.) These include calcium antagonists (or calcium channel blockers), such as diltiazem (Cardizem, Dilacor), nicardipine (Cardene), nifedipine (Procardia), and other medicines used in blood pressure treatment, such as methyldopaMedications that thin the blood, such as low doses of aspirin or dipyridamole (Persantine), are sometimes helpful. Some patients with persistent symptoms can benefit by adding a medication called pentoxifylline (Trental), which makes the red blood cells more pliable and thereby improving circulation. Take care. Hope my answer was helpful, if yes, vote helpful. Regards, Dr Olgeta Xhufka ( general and family physician ).
