Is effect of numbing injections muscle paralysis?

Yes. : Medications used in numbing injections temporarily interrupt the entire function of the nerve injected. If the nerved which was injected is a sensory and motor nerve (meaning that it goes to/serves a muscle), the injection would cause numbness and paralysis. Ortho patients who have had "blocks" to improve pain control post-op experience this effect commonly.
