How to Know if I Have Plantar Fasciitis
You may have plantar fasciitis if you notice sharp, stabbing pain in your heel, especially with your first steps in the morning or after sitting for a while, that often improves as you move but returns after long periods of standing, walking, or exercise. Many patients also experience tenderness along the bottom of the foot, stiffness, or pain that worsens when climbing stairs or wearing unsupportive shoes.
Heel pain that may not be plantar fasciitis can include:
- Pain at the back of the heel that worsens with activity, often linked to Achilles tendonitis.
- Swelling, bruising, or sudden sharp pain following an injury may suggest a stress fracture.
- Burning, tingling, or numbness in the heel could point to nerve irritation or tarsal tunnel syndrome.
- Stiffness and joint pain in the heel or ankle are commonly associated with arthritis.
- Thickened, callused skin with tenderness, sometimes caused by a heel spur or pressure from footwear
