4. Frequent headaches
One of the least-mentioned symptoms of this condition, specifically acute leukemia, is regular headaches that happen to be very severe and last for long.A number of leukemia patients recall waking up to severe headaches mostly accompanied by general achiness and profuse night sweats. Paleness, often appearing as white as a sheet, may come along with the headaches. The reason behind these headaches is the restriction of the flow of blood to the spinal cord and brain, similar to the way a migraine is caused, when the blood vessels become narrow. In some dire cases, the patient may experience seizures as well.
