The reasoning behind the foot warnings is worth reading in a source's own words.
Two named causes
The CDC says nerve damage and poor blood flow, another diabetes complication, put you at risk for developing a foot ulcer (a sore or wound).
What the sentence is saying
It names two separate problems, nerve damage and poor blood flow, and it names one outcome, a foot ulcer. The sentence defines an ulcer as a sore or wound. It describes a risk, which is different from saying every person with diabetes will develop one.

What to confirm, and with whom
Ask your diabetes care team, and a foot doctor, whether nerve damage or poor blood flow has been checked in your own feet. Itasca readers can ask at a nearby office. The point is to move from a general risk to a statement about your feet.
The phrase people skip
"Another diabetes complication" is easy to read past. It tells you poor blood flow is itself a complication, listed beside nerve damage and not folded into it. When you ask about foot risk, ask about both.
