A limb that abruptly becomes cold, pale, blue, or numb

Is any of this happening?
Be seen today
Contact a clinician promptly for a new foot wound, increasing redness or drainage, skin color changes, new rest pain, or a clear decline in walking ability.
People with diabetes or reduced sensation may not feel an injury, making regular visual foot checks especially important.

Follow-up may include review of walking ability, foot symptoms, medicines, tobacco use, blood pressure, cholesterol, and diabetes control.
After revascularization, clinicians may check pulses, ABI measurements, or ultrasound findings.
The schedule depends on the procedure, symptoms, and overall health.
Routine appointments are appropriate for stable symptoms and ongoing risk-factor care.
Every sign above is quoted from the sofidex article on Arterial insufficiency. If you are not sure, err upward — it is always reasonable to be checked.
