Er500-c1, I doubt the year makes much difference. Compression fracture to L1 several years ago and considered stable. Mildly osteoporotic, particularly measured on the neck of the femur. 26 yrs old, 6 ft tall, skinny enough to make Champ look twice (possibly) I shouldn't have a sore back from riding, surely. Is this happening when I do my boots up, could it be the backpack I'm wearing, hunching under the screen when the wind gets whistly or what? How would I even begin to address this? Having a word with the quacks might make some sense if my spine is de-laminating furiously. Do you lot have any advice about posture? Cheers, Cat
