I'm not sure which disc it is, but my mother is dealing with a herniated disc right now. Stretching and working out at Curves (http://www.curvesinternational.com) is helping some, but it is a long way from better (if it will ever be better).

I believe swimming is an encouraged method of exercise. The two roadblocks seem to be (a) she feels the Timpany Center (http://bayarea.easterseals.com/site/PageServer?pagename=CABY_ESCC_Intro) pool is far to drive to & (b) she does not feel comfortable swimming alone in the pool at her SJ house (which may also still be cold this time of year as it is solar heated with blankets which are currently off).
