I'm suffering from cervical spondylitis from 2 years. Have taken numerous physiotherapy, chiropractic sessions. Spinal decompression helped me a lot for an year. But recently I'm suffering my dizziness and rapid heart beat suddenly and head ache. I have taken my neck X ray and my cervical curve is in S shaped. I have read in one of Heath journal Cervical problems some times lead to rapid heart beat due to compression of Vegas nerves at C1 and C2. I have consulted cardiologist to check my heart condition, doctor said everything is fine. But I just wanted to make sure is it becoz of the cervical issue my heart rate increases with dizziness and goes away after sometime. How to diagnose it properly. And can the S curve be reversed to normal curve.
