Lymphatics: May just be a coincidence or could be inflammation of some of the Lymphatics and lymph nodes in your Scilla secondary to the flu shot. Should improve over a week of two as the inflammation passes.

Reaction to vaccine: Not unusual. As long as this gets better and disappears within a few days you should be fine. This is probably a lymph node enlarging in reaction to the vaccine stimulus, and doing its job appropriately. If it does not get better or seems worse then get to a doctor ASAP.
