When should I see a doctor?
See a podiatrist if pain persists past 2 weeks, prevents normal activity, or is accompanied by red-flag symptoms (warmth, swelling, numbness, inability to bear weight).
Can I treat this at home?
Mild cases respond to RICE protocol (rest, ice, compression, elevation), supportive shoes, and OTC anti-inflammatories. Persistent symptoms need professional evaluation.
How long does it take to heal?
Most soft tissue injuries resolve in 2-6 weeks with appropriate care. Bone injuries take 6-12 weeks. Chronic conditions need longer-term management.
