Plantar fasciitis is one of the most common causes of foot pain, affecting over 10% of the population. For that 10%, they will experience immense stabbing pain from inflammation of the thick band of tissue that runs along the bottom of the foot and connects the heel to the toes. The think band of tissue is the plantar fascia.
Plantar fasciitis usually occurs within the first few steps in the morning and will subside over time and may be exacerbated with activity throughout the day. People who run a lot, are on their feet a lot or are overweight are usually the most at risk of getting plantar fasciitis.
Plantar fasciitis can be managed with ice, massage, minimizing excess stress on the fascia (could mean less running or just avoiding barefoot walking) , NSAIDS, stretching or taping.
It is safe and effective to continue to exercise with an emphasis in non-weight bearing exercise. Stretching is also very effective and encouraged. The most popular stretches would be heal raises and rolling a lacross ball across the fascia on the bottom of the foot.
