What is a Plantar fascia strain?
A Plantar fascia strain is a tear of the fascia which forms part of the arch under your foot.
The plantar fascia, or arch ligament, is a band that runs from under the heel to the front of the foot. A strain or rupture to this is quite common which may cause a small lump to appear.
A plantar fascia strain might result from one single traumatic incident, resulting in sudden pain, or may gradually occur over a period of time.
Treatment of a plantar fascia strain
Rest is important to allow your injury time to heal. It may be difficult to rest your foot so use crutches if necessary to take the weight off the injured leg.
Apply a cold therapy compress wrap as soon as possible and every 2-3 hours for 15 minutes at a time.
Later this can be reduced as the acute phase passes, which will be 48 hours or more depending on the severity of the injury.
Tape the arch of your foot to provide support and protection to the injuryed tissues. Our simple foot arch taping technique significantly reduces the load on the fascia, aiding the healing process.

Your physio may use electrotherapy such as ultrasound to reduce pain, swelling, and inflammation. This applies high frequency sound waves into your tissues providing a micromassage effect.
After the initial acute phase, sports massage may be beneficial in helping to restore the plantar fascia to its original condition and improving flexibility.
If the fascia is allowed to tighten up then plantar fasciitis may come on as a possible secondary condition.

A full foot and ankle stretching and strengthening program are advisable to restore strength in the plantar fascia. Calf stretching exercises, as well as plantar fascia stretching, are important.
If the fascia is very tight then wearing a plantar fasciitis night splint overnight can be useful. A plantar fascia strain injury usually heals well within two to three weeks.
