I had a need to have ACDF on C5 - C7. I didn't know this at the time but went to PT and eventually a trusted Chiropractor friend. My symptoms - pins and needles on thumb and index finger, same with a patch of skin on my forearm, Dull to bad ache on my upper arm, neck pain radiating down to my shoulder. Chiropractor told me it would be great if I could get an MRI for my cervical, he said "more information is better than Less" so I did. Sever stenosis at several places. Chiropractor was working me over from neck to lumbar, he actually fixed most of the symptoms with my neck but I think hurt my Lumbar, which was pretty sore. I postponed the neck because it appeared much better, but I developed very weak legs, went to Dr Lopez at Midwest Ortho at Rush, a referral from my physical therapist, he reviewed MRI and said I needed ACDF, making it sound like the Cervical was the source of my weak legs. I persisted with having the rest of my spine scanned, and that's when he found a huge hernia at T8 - T9 which was the cause of the weak legs. Long story to say that my Chiropractor DID relieve me of 90% of my cervical symptoms till they started coming back about 2-3 months later, I had stopped with the Chiropractor manipulation after my neck symptoms felt great, but I believed my Lumbar was very sore and that was the reason I stopped the Chiropractic manipulations. Neck lasted 2-3 months before symptoms started returning .
