I had a severe case of plantar last spring while vacationing. It was so bad that my leg was inflamed to mid-calf. I opted for medical intervention when I returned home. The most excruciating 20 seconds of my life was a cortesone injection directly into the base of my heel [I would have given up any state secrets I possessed during that time], and in less than an hour my foot pain was gone. By the next morning all swelling and redness was gone. Now I do some stretching and foot rolling exercises each morning, and wear supports in my shoes. The alternative would have been to stay off my feet for 14 days.
