My son just had his second surgery for what he was told to be plantar fascitis. His second surgery with a well known sports doctor, for our area, told him 95% of heal pain is misdiagnosed and is not plantar fascitis. It is tarsal tunnel. And from what he has been thru, I will find alternatives before I would go thru what he has. He has been in a boot, or on and off crutches since June of 2015.
