Fred,
Thanks for the concern and advice. Back feels great lately, best in years. Normal activities (hard), including riding/racing, skiing no problem. I know some guys don't beleive in chiro (I was one for awhile) but it REALLY helped. I know you can't see the disc but you can see the proximety of the vertebre. Funny thing, this is an old condition and was NOT what was causing my problems. First sign of trouble though I will push for an MRI. Now to fix my clavicle.
