I agree, i think the spurs/faciitis could be linked also to hormonal imbalances as i've just experienced these past few days the heel pain again after many weeks of not...just as menstruation occured and progesterone and estrogen go to their lowest levels.
That's twice i've noticed it occurring during low hormone cyclical levels.
Obviously having impaired adrenal function could really affect that balance too giving pain most of the time for some.
