Safety should be your first priority when working out. To help avoid chronic problems, it is important to recognize and heed warning signs that something might be wrong.
Symptoms often begin within a short time after starting exercise, typically diminish 30 minutes to four hours afterward and are usually brought about during moderate- to high-intensity exercise, such as jogging. Exercising in a warm or humid environment or after eating certain foods has been found to increase the likelihood of attacks.
Some risk factors associated with developing plantar fasciitis and heel spurs include sudden changes in intensity or length of workouts, decreased flexibility in the foot and ankle, gait abnormalities, weight gain, improper footwear and tightness in the Achilles tendon.
