I'm so sorry

Backs are so weird like that. Your recent setback may not have even been caused by anything you can pinpoint. I know some mornings I just wake up and it's a "hurt" day, unrelated to anything. I feel very lucky I've found the pilates/massage/therapist woman that I work with because some days I'm convinced she knows my back better than I do.

Just thought I'd mention, having a hammock (with no spreader bar, hung tightly enough that I can lay level across it) has really, really helped in relieving pressure for me. To the point that I rave about it all the time so I apologize if I've brought it up too often here Since you're supported evenly with no pressure points it seems to release nerves and muscles that get aggravated by my normal posture.

Also sort of random, but you may want to think about things you carry on a normal basis. I don't even carry a purse most of the time any more because even that slight imbalance seemed to have exaggerated effects.

Hope you're doing better soon! *careful hugs*
