Heels spurs occur when calcium deposits build up on the underside of the heel bone, a process that usually occurs over a period of many months. They are often caused by strains on foot muscles and ligaments, stretching of the planta fascia, and repeated tearing of the membrane that overs the heel bone.
Plantar Fasciitis occurs when the thick, fibrous band of tissue – called fascia – that reaches from your heel to your toes are overly stretched. When the fascia is overly stretched, tiny tears can occur in their surface. This can cause pain and inflammation.
