I went to a NUCCA doctor (chiropractor) who adjusted my C1 (atlas) in my neck. Since then, I have been super dizzy, unable to function, and sleeping all the time. I went to the ER after trying to workout and became extremely dizzy and unable to walk straight. The NUCCA doctor has never had a patient with these symptoms. While at the ER, they did a CT scan (normal) and an EKG (not normal). My heart rate was 46-48. They said that I should follow up with my doctor...which whom I will see in a few days. I am an athlete and wear a HR monitor when I workout. My normal resting heart rate is 58-62. I tried running and my low HR was 30, averaged 68, and high was 90 for a 45 min. run! Afterwards, I was extremely off balance and slept for 4 hours. I really thought my heart monitor was broken....but maybe it's not. Anyway, I am wondering is it possible that the neck/spine manipulation caused my Vagus Nerves to be stimulated????? If so, how do I have this corrected? I cannot stand the condition that I am in!
