anyone had a muscle biopsy and result of type 2 muscle fiber atrophy?

hey everyone!
i am a 26 year old female i was healthy december 2024 and January 2025 it all came tumbling down and hit me like a rock!!! i have been searching for answers for a year now with little diagnosis along the way but no one can figure out what the main source is i got diagnosed with spinal stenosis, herniated disc, spondylolisthesis, raynaud’s phenomenon, lyme disease, and prurigo nodularis. none of these really correlate with eachother and my symptoms aren’t textbook. i have done a myositis blood panel 3 times and everytime my MI-2 is positive and keeps going up. my CK is always normal ive had 2 EMGs that were abnormal and both were widespread increased insertional activity dennervation without reinnervation and CRD + myotonic discharges. i recently had a muscle biopsy. and all it showed was type 2 muscle atrophy and does not match with myositis. so i am very confused and wondering if anyone else has gotten a muscle biopsy with the same result and what you got diagnosed with ? what your next steps were? or any advice or help would be greatly appreciated!!
