My doctor said that my arch is too high and as a result the middle of my foot hurts once it is lifted of the ground. why is this happening?

Pes cavus: High arch causes increased pressure on the front and back of the foot. This can cause pain, calluses, arthritis, deformity. Sometimes genetic causes, sometimes spinal cord/tethered cord issues.

Pes cavus: An excessively high arch can cause the muscles to work harder when you're walking or wearing high heels. This can be a fatigue of the muscles and can usually be easily treated with orthotics. If you're also working out a lot you might be dehydrated or need electrolytes.
