Off topic, but heel spurs are a problem that just doesn't go away. You can eliminate some of (maybe most of) the symptoms with cushioning and reduced walking, but once formed, a heel spur just doesn't resolve without surgical intervention. Plantar's warts affect soft tissue and that can resolve with treatment. That said, the easiest and usually most efficient way to eliminate the pain from either condition is with dual density cushions for the heel. Here is one type, I used to prescribe them with great success. YMMV and this is NOT medical advice, as you should always consult your health care provider for treatment suggestions for your specific condition.
