Craig,

I feel your pain. Mine felt like needles sticking in my heel everytime i stepped.

Relief only came when I:

1) Used regular (daily) stretches.
Not a bad idea anyway as it prevents injury (changing tires, lifting groceries, helping someone in trouble with CPR, scrambling down stairs when some idiot runs a plane into your building, etc).

2) Switched from dress shoes to sneakers (good cross-trainers with good support) and augmented that with supportive inserts.
Not always an option in certain work environments and can be used used all the other times, just switch shoes before entering the building.

3) OTC Anti-inflamatory meds.
Insert obligitory "check with your personal physician first" to avoid any contraindications with pre-existing health problems and medication interaction.

As a nurse I'm on my feet all day so I still have minor flareups from time to time and I attribute that to not doing my morning stretches.

(There are no mistakes, just leasons and leasons are repeated until they are learned).

Wish you relief.
