What Causes Pain And Numbness In The Arms?
Spine issues should be considered.
Detailed Answer:
I read your question carefully and I understand your concern.
If by warning you mean a life threatening heart issue then I do not think that is not the case, not only because of the normal stress test, but also because the symptoms do not indicate something of the kind.
In my opinion a spinal column issue must be investigated. Spinal cord lesions, in particular in the posterior areas, may manifest with such pain radiating in the limbs. By lesions I mean issues such as disc herniation compressing the cord, vitamin B12 deficiency, myelitis, multiple sclerosis (unlikely at your age), trauma etc.
For that reason I think a spine MRI should be the test of choice to be scheduled to search for such a possibility.
I remain at your disposal for other questions.
