New symptom

For the past month I have had a new pain in the area of my spleen (under 10th rib, left side).  It sometimes takes 2 percocets at night to make it tolerable.  It seems to hurt more when I am laying down.  I see the doctor next week so we will see what he has to say.  I am thinking about having an endoscope done to check out this difficulty I have been having (past year) swallowing solids.  Food just seems to get caught and I can bring it back up....weird. Anyway, I assume that my lymph nodes are growing from the tumors.  We will see.
