Please try and diagnose me. Seems the doctors and specialists can’t. Below is my background and main symptoms that I need diagnosed.

Background:

I have had Ankylosing Spondylitis my hole adult life that has caused fusion of my central spine T6-T12 and SI joint bilaterally. This was a painless process until this year when intractable pain hit. I was put on Celebrex/Pantaprozole and Humira. Note: Humira is linked to nerve damage and MS like symptoms. Stopped Humira 2 months ago and symptoms are not going away.

Blood tested for everything and shows normal vitamin levels (except D) and normal glucose, and normal Celiac.

MRI has shown I have a 3mm herniation in my disc at C5-C6 as well as a fairly narrow spinal canal at that area. No cord compression on MRI though.

Nerve conduction studies show minor carpal tunnel and tarsal tunnel bilaterally. This all started suddenly

It is almost like all of my nerves have become inflamed or irritated. Is there a systemic disease that causes tunnel symptoms in both hands and feet? Or causes widespread nerve damage/inflammation?

Current Main Neurological Symptoms

-Paresthesia in both hand and both feet that is on and off and ranges from mild to severely painful burning sensation.
-Severe burning sensation in both wrists and both ankles that comes and goes.
-Tinel sign all over both arms and legs (at wrist, elbow, bicep, forearm, ankle, knee….etc)
-Sudden severe Urinary urgency despite negative urine culture. At its worst it was 24Hrs a day and I did not sleep for a solid week. Was going to the bathroom 100+ times. Problem has subsided and is quite minor now.
-Bladder symptoms and sensory symptoms would alternate like a switch.
-No weaknesses anywhere

Current Pain Symptoms

-Severe pain in thoracic spine that is always there
-Pain in neck with minor stiffness and loss of ROM.
-Pain in lower spine around L5
