Thanks for the additional information,

This sounds to be like raynauds phenomenon which is a condition in which the arteries or the vessels supplying the fingers constrict cutting off blood supply to the finger for a short period of time and thus causing the fingers of the hands to turn white and then blue. This cna be an indicator of an underlying disease or can be an entity by itself.Once the spasm of the arteries resolves the fingers turn back to red due to inflow of blood back into the fingers.

Now as i said this can indicate any underlying disease such as RA or even scleroderma which would also show thick skin and other signs as well. This can also indicate another disorder of the blood vessels such as vasculitis and this can cause vessels to be affected all over the body. If you are a smoker then this pehnomenon would occur more commonly and you would also be more prone to developing a disease known as Buergers disease which causes damage to the small vessels in the hands or feet.

Now sometimes no known cause is present for this problem and in such a case raynauds phenomenon is termed as idiopathic and treatment is started after ruling out all the other possible causes.

the treatment is mostly conservative with avoiding factors which can trgger this like cold, trauma, certain drugs, smoking etc. ALso drugs which dilate the blood vessels such as calcium channel blockers are also used. Lastly surgery can be dopne as well to prevent the arteries from going into spasm.

here is some detailed information about raynauds phenomenon,
