Undiagnosed injury from a backpack vacuum in my upper back clavicle near t2. it's been a year and doctors have no answers. it's one pinpoint spot that stings and burns, makes me unable to turn head or move arm. mri, electromyography and xray normal.

See pain doc: Localized pain without x Ray findings can be a problem for the patient and practitioners when cause is elusive. I suspect the real issue is from your cervical spine with pain referral. Get an x Ray with full flexion and extension views of c spine to look for ligamentous laxity. Get trial of local lidocaine injections (or buy 5% topical at pharmacy) to T2 area. Use neck bolster during sleep.
