Hello, I have studied your case. As per your symptoms cause can be cardiac related. There is possibility of cardiac congestion. I would like to ask some more detail question about your symptoms. Was there sweating associated with it? Do you have history of hypertension? Another possibility due to compression of this nerve root there is pain in your arm. You need to rule out cardiac cause by ER check up I will advise you to do MRI cervical spine, and EMG- NCV [nerve conduction study] X ray may not show details. For these symptoms analgesic and neurotropic medication can be started. Till time, avoid lifting weights, Sit with support to back. You can consult physiotherapist for help. Physiotherapy like ultrasound and interferential therapy will give quick relief. I will advise to check your vit B12 and vit D3 level. Hope this answers your query. If you have additional questions or follow up queries then please do not hesitate in writing to us. I will be happy to answer your queries. Wishing you good health. Take care
