hi..thanks for your query.
From what you mention , I do not think that Raynauds,although significant , is the cause of the itching to happen.You can have a look into the toe area an see if you have any eruption over there e.g..rash
, scaling etc.You should always check for the contact factors in the area like socks,shoes,stockings ,winter boots so as to minimize any allergic contact dermatitis
by avoiding synthetic and colored material as much as possible.
Continue using medicated emollients in the area several times in a day.Mild topical steroids
can be added as as when required for 2-3 days in the area.you should consult a dermatologist
is there are any visible changes /lesions on the skin.
hope this helps.Take care!
