Abdominal Pain
Abnormal WBCs can accumulate in the spleen and liver, causing the abdomen to swell and make you feel pain. Abdominal swelling of this type can also reduce your hunger or making you feel full at the start of a meal. Tightening the spleen frequently causes pain in the right upper abdomen, while liver involvement often causes pain in the upper left abdomen.
If there is no apparent cause of abdominal pain, you should step forward and consult your doctor for further investigations to rule out the underlying diagnosis.
