S-T-R-E-T-C-H. Stretch your feet and calf muscles. Flap you feet up and down before you get up in the morning or after you've been sitting awhile. Avoid pounding your heels: no walking in bare feet or wearing flat shoes. Use gel heel cup inserts. No high-impact activities [jogging, jumping]. Ice your heels up to 20 minutes, 4 times a day [can roll foot over frozen oj concentrate can].
Stretch your calves. You most likely have plantar fasciitis. Here is the straight up answer. Stretch your calves 3 min. 3 times everyday and you will get over it. Everything else you try might make it feel better, but when it comes to correcting the cause, your tight calves, all else is just busy work and expensive. Stretch your calves, save your feet.
Wear a . Night splint.
