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
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.
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.
