Over-the-counter medications for pain may help ease inflammation and pain. Other home treatments include doing stretching exercises for the plantar fascia and the Achilles tendon. Exercises include rolling the foot back and forth over a tennis ball or some other round object, like a frozen water bottle. Applying ice to the painful area and wearing a night splint to stretch the calf and arch of the foot while sleeping is other home therapies. Also, be sure to wear shoes with good arch support.
