I Was Told I Have Reynauds Disease In My Hands. So That Could Be Your Pain. I Have Also Seen Where Reynauds Is Thought To Rsd. Ha! My Doctor Says ... What Difference Does It Make What They Call It, Neither Can Be Cured! I'm I With Him. I Try To Crochet And Do Other Things To Keep My Finger As Limber As Possible And Work Around The Cramping Up. I Also Use Heat On Them And Wear Only Leather Gloves To Contain The Warmth.
