I have been pushing my walks alot lately and have developed extreme pain in one foot following my last walk which was about 7 miles. I have increased quite recently my range and time that I walk to about double my average and I think I have damaged something. Dr. Google seems to say it's Extensor Tendonitis. I haven't seen my doc yet but it sounds pretty likely. Have any of you dealt with this? I understand it's a common runner's injury. If you have had it, how long does it take to heal? I'm gonna go nuts not walking plus I lose those extra calories. Any insight would be helpful.
