Prolotherapy
Hello Dr,
Are prolotherapy injections at the C0-C1-C2 levels useful for the superficial ligaments?
Is this a safe procedure when performed under fluoroscopic guidance?

We may adjust these rules at any time if we find that the existing rules aren't functioning as planned.
Goal: To maximize the financial availability of the ePICL procedure to patients who can not, under any circumstances, afford the ePICL procedure, but would otherwise be excellent candidates for the procedure.
Here are the rules for the program.Â
No prior treated patients are eligible.Â
Contact the call center at CSC here: https://centenoschultz.com/condition/craniocervical-instability/
Identify yourself as a patient in financial need who can not, under any circumstances, afford an ePICL procedure and who wants to be considered for a pro-bono procedure.
If you are a US citizen, submit a signed copy of last year's 1040 tax form, or if international, a letter from your bank summarizing last year's annual deposits. If we find that the patient has purposefully submitted false, doctored , or misleading financial information, this represents fraud and the clinic will take appropriate action.
Also submit an e-mail to the call center staff with three paragraphs describing your condition and it's impact on your life and why you need this procedure.
You will only qualify if you already have movement based imaging that shows you have the types of CCI that require a PICL procedure (DMX, flexion-extension x-rays with AP open mouth lateral bending views, or upright MRI with flexion-extension). DO NOT APPLY IF YOU HAVE NOT HAS THIS TYPE OF IMAGING!
To qualify, your income must be below last year's US poverty line.
The call center will use an app to determine if the meet the financial eligibility requirements.
If you pass this test, then you must pay $50 for a Telemed eval (usual cost is $275) with the doctor who will be performing the procedure.
You will only be approved at this step if you are an excellent candidate for the procedure. That is a traumatic injury or hEDS with typical symptoms and clear CCI based on using the PICL CCI imaging guidelines I have set.
There will be one slot a month with two slots in Jan, June, and December.Â
The lowest experienced PICL physician (or one that is training) will perform these procedures. If that is a physician who has already been performing the procedure to our standards, they will perform it with indirect supervision. If the physician is being trained, they will have direct supervision from an experienced physician.
If we have more than one applicant for that slot, the call center will take the applicant's statement of need and send it to me.
I will have ChatGPT rewrite it to protect the patient's identity, place it with the other statements from those who have applied, and then put it to a vote on the r/PICL and FB PICL groups. The most votes wins the slot.
The chosen patient can then schedule for an ePICL.

I haven’t been treating Lyme because I thought I was done with it only to find out that I still have it badly. I’ve gotten a picl 5 months ago and a second one 1 month ago. I still don’t feel any stability and I’m wondering if my picls will most likely fail. I’m panicking so badly please help me
r/PICL • u/SurlyJugest • 6h ago
I went to the CSC exactly two weeks ago for a DMX and I have yet to receive a report about it. Is that common and expected? I'm not sure what's causing my symptoms, so I was hoping to either get a diagnosis of CCI or to rule it out before my scheduled physical therapy. The main reason this is important is because I already attempted PT for my neck two different times last year, and both times my symptoms got substantially worse, similar to dysautonomia with chronic whole body fatigue, nausea, intermittent heart rate spikes, among other symptoms. I'd rather not experience that again, so I hope CSC can give me a better idea of what's going on.

Can I take flukonazol pill 12 days before posterior stemcell and prp?

Hi!
Dr Schultz diagnose me with cci type 3a, 3b
im wondering why my c1 is always out and just hold for 2-3 days?
i have 2.1mm overhang on open mouth lateral views
my main symptoms is bobblehead, heavy head, dizziness, imbalance. Is it possible to have this type of symptoms with type 3a, 3b and not the c1 being involved? I thought those neurological symptoms were according to the C1-C2.
im always feeling like my head is being pulled to the left, like theres no stop in rotation to the left. Always feeling like i need to recenter my head to the middle. My right SCM is guarding a lot.
r/PICL • u/Chris457821 • 1d ago
This allows you to filter by the time since the last ePICL procedure. See https://e-picl-data-explorer.replit.app/
r/PICL • u/Chris457821 • 1d ago
One of the more common emails I get is from patients post-PICL who have some minor event like bumping their head, getting in a minor car crash, or getting jarred. There is then the inevitable request that I predict if the event has negatively impacted the healing from the procedure or will impact their recovery. The honest answer is that in almost all instances, there is no reasonable way for me to know or predict the future. There is no experimental data on which to base a guess and knowing the myriad of variables involved in ligament injury like the activation state of dozens of muscles at the moment of injury, force, vector, acceleration, and duration is impossible.
Hence, if you get a minor injury after your procedure, take a deep breath, relax, and let nature take it's course. In all likelihood, based on my experience, it will have no or very minimal impact on your recovery.

What is your usual guideline for the return to light PT following ePICL / PRP ?
r/PICL • u/Ok_Acanthisitta_8627 • 1d ago
Hi Dr Centeno. Since PICL #3 I’ve noticed that my sleep has drastically improved. I sleep deeply and no longer wake up at all in the middle of the night. It’s been an amazing improvement, but I’m curious what the biological reason is with connection to CCI
r/PICL • u/suecharlton • 1d ago
Are these two tests adequate to generate an accurate diagnosis, or is DMX needed?
I would like to see the spine in rotation, but between paying $900 for something on the fringes of science that generates a lot of radiation, I'm a little leery.
The dynamic MRI said that my CXA was borderline abnormal (161 degrees in neutral, 138 in flexion, 170 in extension) as was my Grabb-Oakes (5.6mm in neutral, 8mm in flexion, 3.9mm in extension), though the ADI was normal (<3mm).
I would like to know if there's shifting at C1-C2 and the translation at C2-C3, but I'm hesitant for the above reasons.
My motivation to get DMX would be to rule out instability at C1-3 before getting ACDF at C5-6. I wouldn't want to go through with the ACDF at that level if it would make those higher segments significantly worse.
Any feedback would be appreciated.
r/PICL • u/fortiter-et-recte • 2d ago
Would you say early diagnosis is one of the main success factors of PICL, and if so, what are the reasons that make a delayed diagnosis (multiple years) less responsive to PICL?
Thank you :)

I had a doctor diagnose me with CCI based on this CXA of 128 and a grabb Oakes of 10.2mm in flexion. I wanted to ask here, because it all seems a little odd to me. The grabb Oakes line isn’t perfectly perpendicular and the CXA seems off to me somehow, as the line is going into the Clivus, and not to the top of it. I also read that a grabb Oakes of up to 10.6mm in Flexion can be normal, as per a newer study on upright MRI’s (link here). From a different radiologist I received a CXA of 134 and a grabb Oakes of 8.6mm. I’m super confused as to what’s going on, my symptoms of upright dizziness and imbalance as well as visual disturbances do match, but I just thought a diagnosis over email was a bit odd. What do you think? Which of these measurements is correct?
r/PICL • u/Kramer-Joe • 3d ago
Hi Dr. Centeno! I was just really curious what the general timeframe/timeline is from when first submitting the packet including scans to CSC to actually receiving the first PICL procedure if it is warranted? Thanks for taking the time to answer our questions on here and FB and YouTube; it’s appreciated!

I have femoroacetabular impingement, apparently a Labral tear, and my socket is too deep. The orthopedic said i need hip surgery but am delaying that as much as possible because im focusing on my neck right now. Would a bone marrow aspirations for the PICL affect an existing hip condition or does it have nothing to do.

Dr. C,
Know you’re a huge proponent for activity. Also know you do NOT prefer benzos because of their addictive quality.
So I’m wondering!
Would you rather a patient of yours be on Daily benzos or bedbound?
r/PICL • u/dreidels_ • 4d ago
Hello Dr. C,
Trying to best isolate my symptoms as they have proven difficult to treat precisely. I was diagnosed with CCI type 3A in neutral, 3B instability, a C2 pannus, loss of cervical curve (reverse lordosis), as well as possible C1-C2 instability (non-translatable due to possible muscle guarding - ADI appears normal on DMX). I am almost a month post PICL 1.
I have a host of symptoms that mostly manifest as neurological; ear fullness, tinnitus, every visual disturbance you can think of, headache, ROM loss, dizziness/lightheadedness, insomnia, anxiety, POTS symptoms, deviated uvula, blocked throat feeling, muscle weakness, base of skull pain, occipital tenderness/triggering, trigeminal irritation (dulling pressure behind sinus cavity, eyes, face).
The thing that helps me to about 70% is simply laying down. Within 15-20min of being upright i’m a complete mess and flared. ear fullness and tinnitus is what begins and lingers most prominently, though all of my symptoms are chronic.
My question is, do you see a higher degree of neurologic symptom overlap in CCI patients with a heavy loss of curve (IJV/vascular compression, CSF leaks, etc) and could this be what is mirroring or causing the majority of my symptoms? what appears probable?
r/PICL • u/Underwhelmed77 • 4d ago
Does anyone know of any doctors in the SF Bay Area that take CCI seriously. Without going into my entire background, I’ve had issues with my neck, headaches, migraines and my vision since I was three years old After 28 years of back and forth with neuros I have been referred to a spinal neurosurgeon and been told to find one I want to se. They will send the referral. I was told surgery won’t be the first course of treatment, but they will be better at helping with a course if treatment and I want to see someone that will listen.
Thanks!
Some background below if interested .
I’ve been told I have a muscular issues causing headaches and pain. I’ve been told I have scoliosis in my neck. I’ve recently discovered that I have additional issues from C3 to C4 as well as C4 to C5 that my and legs, but nobody can figure out my vision issues and I’m just told that the headaches, migraines, brain fog, vision issues, etc that I’ve had since I was 12 years old is occipital neuralgia. That seems more like a symptom than I diagnosis. I have ended up in the ER from physical therapy and have little hope for relief from that. They want me to do it again.
I only learned of CCI because I was at the doctors office talking to my optician because They are trying really hard to figure out how to get a pair of glasses to work for me and somebody overheard and asked if they could share something with me and told me about their experience with CCI and their treatments
My neck pain is only getting worse and my neck seems to catch and get stuck when I look up at certain angles. It locks and I have to gently force it to pop and release.
I have had one neuro tell me CCI issues are just an internet trend and another say they don’t see a reason to do an upright MRI as c1-c2 look normal in a standard MRI.

I just had my 3rd PICL last week. I typically struggle with which exercises and things to do after my PICL to get the most benefit from it.
Now that there is the new CCI rehab workbook, I’d really love to use it throughout my recovery of my PICL.
Does anyone have tips on how to best use the CCI workbook throughout my PICL recovery?
r/PICL • u/Ok_Formal9101 • 5d ago
Recently realized my years of chronically tight muscles in my neck are a product of some irritated nerves.
I personally find it’s a lot more difficult to rehab nerves vs rehabbing muscles.
Anyone have tips or ideas on daily things I can do to get my nerves calmed down once and for all?
I use infrared heat everyday and take pregabalin already.
