Hi.....yes, to me it sounds like you have Raynaud's. It's a constricting and then dilating of blood vessels in the extremities (fingers, toes, nose, ears..), and considered an autoimmune disease or syndrome. Do you have a job where there is repetative motions? Are you on the computer a lot? Do you have high stress?
I would suggest you definitely get to a doctor (neurologist or rhumatologist) to have it checked out properly. Treatments might be available for you to help.
I read that B vitamins are helpful...especially niacin. One must be careful to not use a very high dosage, but worth doing proper research.
I hope you improve, but I don't think there's a cure. That's why I would express doing your research.
Check out other boards on this site as well which would be more specific to your needs.
Best to you,
quincy
