Red cell production increases. What Causes Sickle Cell Disease. It happens when the sickle-shaped red blood cells that cause the condition get stuck in small blood vessels and block blood flow.

With SCD the red blood cells have an abnormal C shape. These cells do not last as long as normal round red blood cells which leads to anemia low number of red blood cells. Bone and joint damage.

When patients with sickle cell disease SCD present with back pain physicians often assume that their pain is related to an acute painful crisis or to chronic pain caused by bone infarcts in the spinal column resulting in H shaped vertebral bodies. The sickle-shaped cells can also stick to vessel walls causing a blockage that slows or stops the flow of blood.
