This symptom is closely related to fever because it is a way our body has to increase body temperature. In simple words, inflammatory mediators reach the brain and trigger certain areas that give out the signal of increasing body temperature. To execute the order, the muscles in the body start performing jerking movements similar to what we do when it’s very cold. This is meant to increase body temperature and often felt when the fever reaches its peak. This is another common symptom of leukemia, but should not be neglected as we mentioned when talking about fever.
