My PCP won't refer me for specialist or authorize MRI

First I had surgery for severe nerve compression in 2021 at L4-L5.

I've been suffering from neck and shoulder pain for the last ten years or so. I've had 2 cervical epidurals and 2 facet RFAs by pain management without much relief. I was told they couldn't do anything else and might be muscle related. I've been getting botox injections in my neck without much relief.

My latest setback was about 2 weeks ago when my lower back and legs started to hurt very badly and I couldn't walk so I went to the ER. They did a CT and gave pain meds and a walker. I also had neck and shoulder pain that increased this day. I also had numbness and tingling in my feet, arm and hand.

My impression for the CT is below...
IMPRESSION:
1. BULGING DISC WITH DISC PROTRUSION AT L2-L3, MODERATELY
COMPRESSING THE THECAL SAC
2. BULGING DISC AT L4-L5, MILDLY COMPRESSING THE THECAL SAC AND
CAUSING BILATERAL SUBARTICULAR RECESS STENOSIS
3. MILD BULGING DISC AT L5-S1

My last cervical MRI was done in 2022 and these are the impressions below...

C1-C2: Normally aligned, without stenosis.

C2-C3: Partial disc desiccation, without loss of disc height, disc
herniation or spinal stenosis.

C3-C4: Partial disc desiccation, mild diffuse disc space narrowing,
and small left uncovertebral spur contributing to mild left neural
foraminal encroachment. No sign of residual posterior disc bulge.

C4-C5: Partial disc desiccation, mild diffuse disc space narrowing
and small left uncovertebral spur contributing to mild left neural
foraminal encroachment. Previously seen small central disc protrusion
is no longer seen.

C5-C6: Partial disc desiccation with interval mild diffuse disc space
narrowing and small interval central posterior disc protrusion
partially effacing the ventral subarachnoid space, without cord
compression or significant neural foraminal stenosis.

C6-C7: Partial disc desiccation with mild disc space narrowing
interval small central posterior disc protrusion partially effacing
the ventral subarachnoid space, without cord compression or neural
foraminal encroachment.

C7-T1: Partial disc desiccation, without significant loss of disc
height, disc herniation or spinal stenosis.

I was given a steroid dose pack which has helped but I'm still in pain and doing anything just makes the pain flare up. I was given a catheter by my PCP because it was extremely difficult to pee but that passed a day later thankfully.

So I currently have moderate pain in my neck, shoulders, lower back and mild pain in my legs. I have off and on headaches with sudden aches that radiate from the lower back left of my head and ear and up, partial numbness in my right hand, sharp stabbing pain on the left side of my chest, sharp pain and tingling down my left arm, sharp and dull pains off and on in my lower back and legs and tingling in my right foot.

Even with all this she won't prescribe pain meds, she won't order further testing (MRI or newer cervical MRI) or refer me to a pain doctor or to a spine surgeon (as the ER doc strongly urged). She says if I have a flareup I can see her to get a toradol injection or get it at an urgent care center if her office is closed or go to the ER if it's severe enough.

I'm at my wits end and don't know what I can do about this. I can change PCP docs but it won't go into effect until May 1st because I have to see her in early April to get my last authorization for another treatment which is very expensive.

Sorry for being so long on this post and am hoping for any advice.

Thanks!
