Possible case of PsA?

Does this sound like a possible case of PSA to any of you?

I've had upper back pain near my neck for about 10 years that I let hang around, never testing or treating it. Also know, I've trained in the gym as a bodybuilding for nearly 20 years as well and never witnessed these symptoms. Now I'm trying to understand a new onset of symptoms, with recent tests Bloodwork, MRI of entire back and neck and X-rays which show the below:

-Herniated discs: C5 to C7
-4 Bulging discs lower back

Received Medial Branch Blocker 2 weeks before all of these new pains began, coincidence?
**Most of my bloodwork returned normal, tests performed: **

-RF: Normal
-C-Reactive Protein: Normal
-Sedimentation:Normal
-Antinuclear Antibodies:Normal
Folates: Very Low
HLA B27 was positive

Currently seeing:
-Spine specialist
-Pain Mgmt - Only for a spinal injection
-GP
-Neurologist: EMG test scheduled for next month
-Rheumatologist: Waiting to see next month
-The spine specialist I'm seeing said there could be a nerve that is impinged. So I received an epidural injection in my cervical area, no relief. I yet to understand how so many areas can hurt

I have no swelling or redness or no stiffness i think... Possibly a little swelling in the fingers, very hard to tell, not enough that someone notices.

My pain symptoms:
-Fingers, toes, and ears feel cold frequently then will warm up
-2nd and 3rd knuckles have pain intermittently
-Some numbness occasionally in my fingers, not as often
-Pain sometimes in the bottom of my feet intermittently
-Sharp Pains on the side or front of ankles intermittently
-Pain in wrists intermittently
-Occasional burning inner tricep a few times, felt like a sunburn almost
-Muscular twitching through body randomly, mainly leg or triceps which is fine doesn't hurt
-Dull pain in knees sometimes
-Back of legs ache some when sitting
-Feet and back of heels hurt if standing or walking very long
-Pain area constantly rotates and is hard to explain the type of pain:
-Pain can be sharp shooting, ache, electric pinch pain, light ache pulses
-Pain on outside of elbow for a few seconds, seems sharp?
-Pain in front of ankles
-Above/Top of knees

All of this came on so sudden, over night... really - most of the symptoms at once

Literally two weeks after i had a nerve block injection this all happened, coincidence i guess

Can anyone relate or theories of what could be at the root of these pains? It's like one week I was 38 years old then abruptly 104
