I have a friend who has red spots all over her legs, they aren t raised and they don t itch, but her legs and feet swell. Her hands also get red and hurt to touch anythings. She has had all kinds of test done, blood work, seen an r hematologist , has a test done for allergys and a biopsy of the spots. Know one can seem to find out what is wrong with her. Do you have any ideas?
