Prednisone
"Great temporary relief from plantar fasciitis.  Suffered with heel pain for 6 months. Was prescribed Prednisone for a severe chest cold, to help with breathing. Next day, heel pain was gone.  Had about a week supply, and had no heel pain for a week. About three days after stopping, heel pain returned. It is NOT a cure, but a much welcomed temporary relief.  All tabs were 20mg.  Three the first day, two the second day, then one per day for 5 days.  Awesome relief."
