Lateral plantar nerve entrapment is a condition that happens when the nerve that passes from the inside of your ankle to your foot (lateral plantar nerve nerve) gets squeezed or compressed (entrapment). The nerve can get compressed between the muscles, bones, and connective tissue near the bottom of your heel. The nerve supplies many of your toe muscles and gives feeling to the outer toes on the bottom of your foot.
Lateral plantar nerve entrapment causes heel and foot pain that gets worse with activity.
This condition is caused by compression of the lateral plantar nerve in the heel area. It can happen if your small foot muscles become larger from running. It may also happen from swelling…show more content… • An electrical study of nerve function (electromyography or EMG).
Treatment may include:
• Wearing a removable boot or splint for foot and ankle support.
• Using a soft shoe insert (orthotic).
• Using ice to reduce swelling.
• Taking pain medicine.
• Getting injections in the nerve area with medicine to reduce pain and swelling.
• Starting range-of-motion and strengthening exercises (physical therapy).
• Returning to full activity gradually. The timing will depend on the severity of your condition and your response to treatment.
You may need surgery to relieve the compression if other treatments have not helped. After surgery, you may need to wear a removable splint or boot for support and eventually have physical therapy.
HOME CARE INSTRUCTIONS
If You Have a Splint or Boot:
• Wear it as told by your health care provider. Remove it only as told by your health care provider.
• Loosen the splint or boot if your toes become numb and tingle, or if they turn cold and blue.
• Do not let your splint or boot get wet if it is not waterproof.
• Keep the splint or boot clean.
Managing Pain, Stiffness, and Swelling
• If directed, apply ice to the injured area:
