I have chest pain with my shortness of breath. I also have both warm and cold AHIA. Taking Prednisone since 1/10. Had first IV of Rituxin on Wed. 3 more, 1 a week. My hematologist has had good results for her patients with Rituxin. Will update when finished.

When your hemoglobin is low, you will be short of breath as the hemoglobin carries oxygen in the blood stream. Chest pain, I am not qualified to assess the cause. Good question for your doctor.
