mono, i know. i've been so sick for so long. exhaustion is putting it mildly, just ill feeling, like my insides are dying from inside out. What might this mean? I know they are on to something, but i know it's not a simple case of mono at 55 years old, and I've been so sick for so long. i see other conditions with it and am conerned about Non Hodgkins Lymphoma.(spelling?)
