Raynaud's

Okay. That raises the possibility of a condition called "sclerodactyly" in which Raynaud's leads to tightness of the skin over the fingers or toes that are affected.

The next question is asking about other symptoms that might be noticed in diseases such as scleroderma and CREST syndrome.

Do you have any of the following

• severe heartburn or swallowing problems

• multiple red spots over the fingers, face or chest that become temporarily pale when pressed

• tiny white flecks under the skin?

Yes, I have one or more of those problems.

No, I don't have those other problems.
