Starting last Thursday, my foot made some good progress. I was able to walk two miles on Friday night between 18-20 minutes per mile. Saturday morning I did more than three miles walking and was able to get below 17 minute miles in the end. I am trodding a fine line right now with the ankle, but can feel that the tide has turned. I just need to avoid overdoing things (which I have a tendency to do).
I saw my podiatrist last night and he is pleased with the progress. He gave me a homeopathic injection in the tendon that is still bothering me but says that I have a relatively mild case of tendonitis since he couldn't palpitate the area and make it hurt. Just keep bracing and working out and listening to my ankle. I hope to build up my walking in April and be back to running in May.
