A swollen, painful leg or foot in a person with diabetes should never be ignored. It can be a sign of infection, a problem with the veins, or a serious foot condition that needs early treatment. In this short video, Elegance Diabetic Foot & Ulcer Clinic (EDFC), Surat looks at leg swelling, foot infection and foot pain in diabetes, under the guidance of Dr. Ashutosh Shah.
Common Causes of Leg and Foot Swelling in Diabetes
- Foot infection or cellulitis: A wound or crack can let bacteria in, causing redness, warmth, pain and swelling that spreads.
- Charcot foot: Nerve damage can weaken the bones and joints, causing a hot, red, swollen foot, often without much pain.
- Vein problems: Weak leg veins can cause swelling that gets worse through the day.
- Other medical causes: Heart, kidney or medicine-related causes can lead to swelling in both legs.
Why Foot Pain in Diabetes Needs Attention
Many people with diabetes have reduced feeling in their feet, so new pain is an important warning sign. Pain with swelling may point to infection or inflammation. Burning or tingling pain can be a sign of nerve damage, which also needs to be assessed and managed.
How EDFC Assesses and Treats Swelling
The team examines the foot and leg, checks for infection and wounds, and assesses nerves and blood flow. Treatment depends on the cause and may include antibiotics, wound care, offloading, protective casting for Charcot foot, or vein treatment.
