Is Flexibiliy As Good As It Seems
Flexibility in extreme cases can actually make you more likely to experience foot and ankle pain. When the ligaments that hold your joints in position become looser than usual, they can make the muscles that work on the same joint, work harder and become more likely to become problematic. There are standard tests for globalised joint mobility, that you can be guided through by your podiatrist.
The treatment for foot pain associated with increased joint mobility can range from increasing strength of the supporting structures, to decreasing the range of motion during an activity. As most sports are based upon repetition, the smallest of "extra" flexibility which may load up other structures can lead to symptoms and injuries very quickly.
Other pain that can be associated with extra flexibility include sacro-illiac pain, achilles tendonitis, forefoot pain, PFJ syndrome or even pantar fasciitis. During pregnancy, your body produces a hormone called relaxin which suddenly increases your flexibility. This is a good example of an increase in flexibility causing an increase in painful presentations.
