This is what I found on the internet.
I do not know if this is factual or not, so please read it with caution. Also, ask your doctor again when you see him/her.

Lymph nodes in the foot are divided into superficial and deep nodes:
Superficial nodes
Also known as epifascial nodes, these drain the skin and subcutaneous tissues. A large bundle of these nodes forms a ventromedial bundle over the dorsum of the foot, which drains to the superficial inguinal nodes.
Deep nodes
Also known as subfascial nodes, these drain the joints, muscles, and bones. These nodes drain into the deep inguinal nodes.

The foot also has two main lymphatic paths from the lower leg:
Fibular route: This path leads to the popliteal node.
Tibial route: This path leads to the nodes in the groin. Lymph nodes in the foot are divided into superficial and deep nodes:
