index finger pain, non stop for past 4-5 years, cant sleep properly. No injuries or sprain. Now finger skin getting light. just on this finger. Have had x-rays and tried different medicines and treatments from doctors, no relief so far.
Intense finger pain and skin getting lighter (whiteness) could be symptoms of Raynaud phenomenon, most likely secondary one associated with underlying condition like some type of connective tissue disease.
Actually, you may have a case of scleroderma associated with Raynaud phenomenon.
