Can anyone help on my medical notes please

Hey everyone, I had a Rheumatologist that i saw a couple of years back and said because of my hurting and my joints are not so good and in a horrid amount of pain, i had MRI scans and X-rays but were all showing ok but she diagnosed me with Psoriatic arthritis. I left clinic as was scared due to my mental health (anxiety and panic attacks i refused treatment) Im now under a new Rheumatologist as im getting worse with my pain and Psoriasis and he says that he's going to get to the bottom of it all once and for all! sent me for X-rays and another MRI of my spine and pelvis, all its shown up as my T7/8 of my spine there is a small posterior disc bulge without nerve or root impingement. He told me on my first appointment he's putting it more down to Fibromyalgia? i had a blood test which he tells me in the report before my MRI that has come back HLA B27 positive? he also put in the letter that he has a feeling there could be a Fibromyalgia element to this? It says the MRI is normal of the whole spine without any inflammatory spondyloarthropathy. I have to see him again on the 22nd November but i was wondering does Psoriatic arthritis show anything with MRI tests? So sorry to ask all this and i hope it makes sense!! thank you for any advice im so grateful i really am!
