I am a 21 year old male and about two months ago I visited a chiropractor (for the first time) for some upper back discomfort and minor posture issues. While performing the conventional adjustments on my back and hips, I didn't feel any relief. It actually felt uncomfortable and sore. He then proceeded to rotate my neck, something that I've seen countless times performed on Youtube. I researched the risks but never considered something would happen to me, a healthy young male. Anyway, he performed most of the adjustments swiftly, and the neck 'crack' felt even more uncomfortable.
After leaving the chiropractor's office, I left feeling extremely dizzy and disoriented. I felt episodes of severe vertigo and my neck felt 'tighter'. I had tingling sensations all over my body and felt nauseous. I eventually returned home and almost fainted, with arms my feeling numb and suffered a major panic attack. The next few days were groggy and any neck movement would trigger a 'pop' or 'crack', encouraging cognitive decline, stiffness, sleepiness and vertigo. These symptoms eventually subsided but if I strained or rotated my neck too fast, it'd typically 'pop' and trigger the same symptoms.
A few days ago I completely rotated my neck and heard a loud pop, and most the symptoms I described earlier returned. I feel like there's limited rotation and movement in my neck, and the adverse symptoms are a little confusing. Neck cracking usually relieves tension and encourages blood flow. Any opinions? I'm concerned and I hope that no damage is done.
