I feel slight numbness on my hand when I pull my traps and flex my shoulders as hard as I can
I think I performed it too hard so pinched traps and shoulders might have hampered blood flow to my hand.
Is it natural to feel it? Should I bear it out until it fade away?

As I repeatedly watch demo video, I found out that the athlete in the video rotate his scapulars a little bit.
But many topics said it is mobility exercise for shoulder flexion, not rotation.
Which is right?
