Hello and hope you are doing well.
The ‘pale’ fingers could be due to an allergen. It could also be due to circulatory problems, temperature problems or a rash. You will need to see if any allergens are triggering this reaction. You may also need to notice if ‘cold’ is precipitating your symptoms. You will need to consult your primary care physician for proper assessment.
Hope this helped and do keep us posted.
are you on any medications, such as beta blockers etc?
