I have had a constant burning sensation on the outside bottom part of my left foot - from the heel up to the middle of my foot. ive had it for about a year but it used to go away - for the last 5-6 months im aware of it almost 24/7. ?

Heel Pain: Burning heel pain is commonly caused by inflammation of the fibrous tissue called the plantar fascia. This condition is called plantar fasciitis. Rest and anti-inflammatory medications can help relieve pain. Physical therapy can provide exercises to help stretch the plantar fascia and reduce workload on the ligament.

Other options : The above is true. Chronic pain can be controlled 90% of the time with a costing orthotics made by a podiatrist. Surgery is last option but effective.
