In general, pain at the elbows/shoulder means you're either (1) early arm bending or (2) pulling too much with the arms moving under the bar.
I didn't really see much early arm bend so it's probably the latter, especially given the neurological symptoms. Probably pinched a nerve either in brachial/cervical plexus.
Gotta improve arm mobility and loosen up anterior shoulder/pecs/etc. likely.
