Hello, this has been going on for over a year now as well as sciatic/lower back pain.. I have also been "treated" for a trapped radial nerve in my neck scalenes area.. im not sure if at all any of these are related, but the tingling in the midback increases if i carry something in that arm, also if im sitting without support on my back or leaning forward.. if i pinch that muscle, i also experience pain and have been told/can feel it is in constant spasm..

also not sure if related, on that same side as you go towards my ribcage it gets extremely tender to the touch.. one oddity i noticed is if i rub over that tender point on the left ribcage, i get a corresponding tingling sensation in my left ulnar nerve at the elbow (i had a left ulnar nerve transposition btw 2 years back, which was before i noticed the back tingling though it provided little relief)..

is this a pinched nerve? perhaps in the thoracic region of my back? what kind of imaging would help in finding out? i have had prior mri's on cervical spine (normal) and L shoulder (bursitis) but none of my back lower than cervical spine.. also as far as EMG's go, i have had them for other recent (year or 2 ago) issues but it seemed restricted only to my arms/hands-can these be used for my back as well

here is a rough location i circled of the tingling/buzzing:
