By far the most common foot condition I see, orthotics can be extremely effective for treating this cause of heel pain. The pain is typically worse in the morning or after a period of rest and may lessen with activity.
Bunions (hallux valgus) can be hereditary but are also impacted by your choice of footwear and the movement of your foot. Orthotics cannot remove bunions that have already formed, however they can help reduce the pain you may experience and can slow the progression of a developing bunion.
Metatarsalgia is a general term for forefoot pain (ball of foot). Orthotics can help reduce the pressure and improve the alignment of the forefoot.
There are many different causes of knee pain. Many of them can be made worse by excessive movement at the foot. When a foot overpronates, the lower leg internally rotates and changes the alignment of the knee. Orthotics can reduce overpronation, improving alignment and functioning at the knee.
Achilles tendonitis is an overuse injury of the band of tissue that connects the calf muscles at the back of the leg to the heel bone. Massage can help reduce tension in the calf muscles and orthotics and/or a slight heel lift can reduce pain and stress, if needed.
Many people have a leg length discrepancy of up to 1cm without having any symptoms or awareness of the difference. However, depending on your biomechanics and the amount of difference in your leg lengths, you may experience hip or back pain due to compensating for this difference. A simple heel lift in your shoes may be all you need to improve your alignment and functioning.
