I have a 16 yo son who has presented with several enlarged cervical lymph nodes greater than 3 cm. with decrease in weight from 160 lbs to 135 lbs., he has periodic n/v, no appetite. Noted hair loss, fatigue, multiple febrile episodes explained per MD as sinus infections and treated randomly with Augmentin or Zithromax, diagnosed with allergies. CBC, CMP, CXR, EBV, HIV,TB all negative. He looks ill. This is a dramatic change in appearance, behavior, energy. States he never feels good anymore, always feels cold and tired
