I am well acquainted with Raynauds Syndrome, as my mother had it over the last 10 years of her life. My understanding of Raynauds is that there is a blood flow issue and extremities become extremely cold, fingers actually turn blue! That is a very different symptom, in as much as mine involves a low burning sensation.
Learning from other ET patients is useful and helps corroborate my own experiences, particularly invaluable when dealing with many unknowns of ET. Thank you!
