No one in my family has had colon cancer
. Three months ago I was diagnosed with mono, which really brought down my whole immune system. I then had walking pneumonia. I had sinus infections in between too, which caused me to take many antibiotics. I have a severely sensitive stomach and the antibiotics ruined my stomach. Ever since than, I have been very nauseous, no energy at all, loss of appetite, and some pain in my left lower abdomen.
