When to worry about leg pain when walking with type 2 diabetes

Type 2 diabetes can affect nerves and blood vessels in the legs. Reduced blood flow may cause aching or cramping during activity that settles with rest, while nerve damage may cause burning, tingling, numbness, or altered pain. Foot problems, joint conditions, muscle strain, and infection can also make walking painful.

Reduced sensation can hide a blister, cut, pressure injury, or burn. Examine both feet regularly, including between the toes, and report changes even when they do not hurt. A clinician may check circulation, sensation, skin, footwear, and blood glucose management.

Wear well-fitting shoes and clean, dry socks; avoid walking barefoot. Check your feet each day and do not cut corns or calluses yourself. Follow your diabetes treatment plan and record when pain begins, where it occurs, and whether rest relieves it. Do not start strenuous exercise until a clinician has considered new exertional pain, particularly if you have reduced sensation or a foot wound.

Contact a clinician promptly if pain is new, worsening, appears with less walking, continues at rest, or interferes with sleep or daily activities. Seek urgent help for a red, hot, swollen foot; an open or discoloured wound; spreading redness; pus; fever; or sudden severe pain with a cold, pale, numb, or weak foot. Also seek urgent care for severe leg swelling with breathlessness or chest pain.

Ask whether the pain is more consistent with circulation, nerve symptoms, a foot injury, or infection, and whether you need a foot or vascular assessment. Discuss safe exercise, daily foot checks, footwear, glucose management, and exactly who to contact if a wound or skin colour changes.
