I am having heel pain in one foot. I sprained my ankle 4 weeks ago with no ligament tears. It is still swollen some and I do continue to have pain from the sprain but not horrible pain. I had some heel pain before the injury but it has gotten much much worse since the injury. I do wear good athletic shoes with thick insole inserts drug store cheap kind). I have a very high arch so do choose shoes with arch support. Having said that I moved into a house with hardwood floors 1.5 years ago and since then do wear flip flops s lot. Maybe that s the problem. Or could it potentially be something more than planters fasciitis?
