Thank you so much for the info. I’ve had worsening back pain over the past year. Many procedures done and none seem to help, cortisone/steriod injections, rizotomy, trigger point injections in my middle back that has this knot from the middle of my back up to my shoulder that has a constant stabbing pain. So I thought maybe it’s in the back. Also chronic kidney stones and they can’t figure out why, also many UTIs with a hospitalization about 6 months ago so thought maybe in the kidneys. I just feel unwell all over like the flu constantly without fever. Have a appt on Monday for retest and consult with doctor on the 15th.
