Sharp pain in the knee or outside the knee usually occurs during or after excercise.
Knee pain often develops because of flat-feet or 'plantar fasciitis'.The misalignment in the foot and ankle causes the knees to turn inwards, which leads to an improper movement of the knee cap.
In time, the hurtful position of the joints causes inflammation and pain.
Knee pain can be cured by correcting the movement of the knee cap. Your podiatrist will do this by supporting the feet with a type of insoles called 'orthotics' into a normal, aligned position, and the re-alignment of upper joints in the leg and pelvis will subsequently follow.
Orthotics provide support for the foot at all times and re-align and re-balance the joints of the foot and higher joints of the knee and pelvis into a natural position.
Another alternative, depending on the extent of the misalignment, is to wear a knee strap. Consult a FootWise podiatrist about the treatment relevant to your specific condition.
The pain itself can be relieved with anti-inflammatories, but the disorder must be treated by a podiatrist to avoid further damage to the knee joints.
