PSA and thoracic spine

Does anyone with severe PsA spondylitis suffer with thoracic center spine issues? My T-7 through T-9 are literally chipping away. My vertebrae’s are pushing into my spinal cord. The pain is unbelievably crippling my daily life. I had a biopsy done last week. They took several bone and tissue samples. Looking for everything. All of my doctors are stumbling for answers. Supposedly your thoracic spine area is NEVER to “give out?” We are seeking all and any help.
