It is easy to think that if you can still walk, nothing is broken. For stress fractures that assumption deserves a closer look, especially for anyone in Mount Prospect deciding whether to keep going on a sore foot.
Possibly, which is why the question is tricky
Walking normally with a stress fracture can happen. Being able to walk therefore does not rule one out.
What the source says
Cleveland Clinic states: "You might be able to walk normally with a stress fracture." The statement is on its page about stress fractures, their symptoms, causes and treatment.
The word "might" matters here. The sentence describes a possibility. It does not give permission to keep walking, and it does not say that walking is safe.
What to check next
Ask a clinician to look at a sore foot instead of using walking as your test. The MedlinePlus page on metatarsal stress fractures aftercare is a useful comparison for what you are told at an appointment.
How the claim reads against the evidence
"I can walk on it" is a statement about the foot's behavior, not a finding. This source says walking can look normal with a stress fracture, so the claim should not carry more weight than it can hold.
