What Causes Constant Dull Headache And Severe Fatigue?
Constant dull headache in back of head. Severe fatigue and I am a type 1 diabetic. I am 56 and have had two failed pancreas transplants. I am a very brittle diabetic and my A1c is high. These things I have always had....but the fatigue and headache is new. Could it be my sinuses because it even hurts behind my eyes.
