Hello Doctor, My age is 32 years I am having cervical spondylitis problem. I am keep doing neck exercises and yoga From past 2 days the pain is more in my upper back neck and some spasm in front side shoulder muscle in upper chest. Is it due to spondylitis or gastric problem. I did take tablet tolpidol. the moment I get pain in left side upper chest muscle I feel dizziness and feel like lying down. What are the best tips for this Kindly help as to why is this happening?
