The only thing I can offer is a small warning. I also was a habitual neck cracker- up until one night where my normal twist had an unfamiliar popping sensation which kind of felt like a muscle snapping. I was then greeted with incredible pain anytime I tried to move my head or just move in general. Had to go to the ER/urgent care that night. The doctor was very straightforward with their advice- there's no reason I should be cracking my neck and I need to stop. I had pulled one of the muscles and it had severely swelled.
I also used to crack my knuckles, elbows, back, etc. I eventually stopped by catching myself in the act, acknowledging that I don't like feeling like I can't control myself, and giving my hands something else to focus on.
Have you looked up any neck strength and range of motion exercises from a Physical Therapist?
You might be able to address your concerns with discomfort, with the possibility of picking up some healthy movements that are effective as replacements for your main stem.
I just looked it up and your doc was right. It seems that it can often follow a chiropractic adjustment because believe it or not chiropractic is not a real medical field, similar to acupuncture and acupressure.
This is enough to make me think twice about cracking it - time for my AuDHD to find a new stim!
If this were me, I'd probably try to pay attention to my posture and body position as I'm starting a task. Once I'm into whatever project I'm working on I'm less likely to notice my posture until I start feeling actual pain.
I've been doing this lately too, after always cringing my whole life whenever I would see people on TV do it. Now it's become a stim with me too, as well as scrunching my toes to kind of crack my ankle - like popping knuckles/wrists, just the foot version.
My ankle now hurts and I'm wondering if I'm doing lasting damage to my joints and ligaments 😔
real treatment: take up yoga, & do it, for real, until you body's self-healing undoes the problem, then keep doing it, so it doesn't come back.
We store stress in our bodies, which is why a chiro can help, as they can release some of it, while we keep storing more & more & more.
You can't correct the problem by treating only symptoms, tho.
yoga's the only corrective that's going to really work,
and it has to be hard-min 3x/week, 4x/week will work much better.
Use Frawley & Kozak's "Yoga for Your TYPE" book to figure-out which postures are required for your metabolism/dosha, & there are countless videos on the web for seeing how to do them.
