Are there lymph nodes along the shin?

Patient: I have a hard, painless lump on my right shin bone. It’s been there for several weeks and my Dr. sent me for an ultrasound. The radiologist said he thought it was an enlarged lymph node but as far as I can tell from online research, there aren’t any lymph nodes in that area of the body. Is the radiologist correct or should I get another opinion?
