In turn, red blood cells with clumped hemoglobin become sickle-shaped, which can lead to pain, swelling of the hands and feet, frequent infections, and eye problems.” So basically, (in my own words) when blood oxygen levels are low, the sickle cell mutation makes hemoglobin less soluble, causing it to cling together. As a result, sickle-shaped red blood cells form, causing discomfort, swelling in the hands and feet, frequent infections, and vision issues.
