No injury,no prior issues- l elbow severe almost shock like bursts of pain enough to make me involuntarily squirm. rapid onset. no activity change. ?

? Neurologic: Some of the historical features you present sound as if there are neurologic. That would represent the lesion at the elbow involving the owner nerve. If the shocklike sensations travel down to your fourth and fifth digit then I would pay attention to this being neurologic in origin. In which case I would then recommend a full neurological valuation. Good luck and well wishes.
