Heel spur and rest

Try to avoid putting strain on the foot as much as possible. Especially in the beginning stages of a heel spur or plantar fasciitis this is very important.

Dependant on how serious the injury is some light form of exercise may be beneficial, but is is best to discuss this with your doctor.

If you still want to keep sporting, you may switch to sports that do not put strain on your feet too much, like cycling or swimming. Still, beware on any strain: Cycling fanatically will put strain on the fascia again. Adjusting the pedals can be wise here.

Also persons with a profession that requires you to stand still on your feet a lot are vulnerable. Again here: try to avoid this, though your boss may not always agree....

Due to the feet being static for a few hours, these first few meters are very stressfull.  Also check the article on stretching for this.
