Hi, I have a swollen lymph node near my jaw on the left side. It has been enlarged and through a recent CT scan, they found larger than normal lymph nodes in the arm pit, neck, abdominal area and 3 in my lungs. They are painful especially around the neck, shoulder and behind my left eye. I noticed I cannot cry normally in the left side. Also in the past, I have had shingles with post neuralgia. Stool is black with blood...Which doctor should I go see?
