At a glance:
- Non-healing wounds can result from poor circulation (PAD), infection, pressure, or neuropathy—often in combination.
- Early evaluation can help protect the foot and reduce complication risk.
- Urgent signs include fever, spreading redness, foul drainage, worsening pain, or black/blue discoloration.
- A limb-salvage evaluation focuses on circulation and the factors that prevent healing.
Why some wounds don’t heal
Wound healing requires adequate blood flow, pressure relief, infection control, and good nutrition and diabetes management. When any of these factors are compromised, wounds can linger or worsen.
- In people with diabetes, reduced sensation (neuropathy) and circulation issues can make it harder to notice injuries early and can slow healing.
Common contributors we look for
During evaluation, we consider multiple contributors including:
- Poor circulation / PAD (reduced blood flow to the legs/feet)
- Infection
- Pressure points and footwear issues
- Neuropathy (reduced sensation)
- Other medical factors that affect healing
Red flags: seek urgent care
Please seek urgent evaluation if you notice:
- Fever or chills
- Spreading redness, warmth, or streaking
- Pus/foul-smelling drainage
- Rapidly worsening pain or swelling
- Black/blue discoloration of toes/skin
- New confusion or weakness
How we evaluate at MINT (limb salvage focus)
We focus on whether circulation is limiting healing. Depending on your situation, evaluation may include circulation testing and imaging.
If blood flow is reduced, we discuss a plan to improve circulation when appropriate, and we coordinate with wound care and other specialists as needed.
Next step
If you have a wound that isn’t healing, don’t wait. An evaluation can clarify whether circulation is part of the problem and what the next best steps are.

FAQs
Can a small sore become serious?
Yes. Small wounds can worsen if circulation is poor or infection develops—especially in diabetes.
How do you check circulation for wound healing?
Evaluation may include non-invasive circulation testing and imaging. Your provider will recommend what’s appropriate.
Do you replace wound care clinics?
No. Wound care is often multidisciplinary. Our role is to evaluate and treat circulation issues that can prevent healing.
How is PAD related to diabetic wounds?
PAD reduces blood flow, which can impair healing and increase risk of complications.
When should I seek urgent care?
If there is fever, spreading redness, drainage, blackened tissue, or rapidly worsening symptoms, seek urgent evaluation.
