i have a very sensitive thoracic spine and ehlers danlos syndrome

when i stress out my t-spine i can get tingling really badly around my shoulders and around my butt

any guesses on what would cause this? thanks!

*ive only had a neck mri and it was normal

my pt thinks my c7 transverse process is too big but i've had 2 radiologists and 2 mri imagers look at my xrays/mri and say that it is normal
