My husband has antiphospholipid syndrome and also takes testosterone injections for low testosterone. Just had blood work done and his hemoglobin was high and has to give 2 units of blood. Also on Xarelto for his auto-immune disease. Doctors seem to think the blood isn't getting through the small vessels. Has been in a lot of pain the last 3 weeks. Could the high hemoglobin count be causing him all this pain?
