Hello! I suffer with Raynauds syndrom but have not been on medication for it, it was suggested but I'd rather not.
What kind of gloves have you been wearing, becuase I find that even if I were to wear 5 layers of gloves it wouldn't help one bit and I'd still get painful fingers, even ski gloves don't work! The solution I found, is to wear mittens, as this provides a 'den' for all fingers which help eachother keep warm.
Also you can buy some hand warmers and theres also 'special' gloves with silver lining I think, something along the context with 'silver' in. Not quite sure though as have never tried this option.
