For the past several months I have experienced a feeling that the bones in my lower legs and particularly my ankles and my hands, are icy cold. My skin feels warm but I feel frozen. One of the doctors I have seen thinks it is hysteria. It is very real. My AS symptoms have at the same time become much worse to the point where doing anything is a chore and I am exhausted all the time. Has anyone else experienced abnormal cold sensations in the extremities and could it be a sign of progression of the AS?
