  45. I've been diagnosed with APS. What are your thoughts on nutrition and exercise to help with this condition?
  46. I'm ten and one-half weeks pregnant, and have had two prior miscarriages. I've had three separate tests showing elevated anticardiolipin IgM (the values were 11, 14, and 18), and my hematologist says that I have APS. But a perinatologist with whom I've just met says that the positive ACL IgM tests are not indicative of APS at all, and that only ACL IgG is related to APS. Now, I'm quite confused! Do I have APS, or not?
  47. I have been struggling with a number of symptoms for almost three months now. It started with a horrible marbley rash on my feet and ankles, with numbness and pins and needles in my arms and legs. I've also had mental fog and some other symptoms.
